NAV integration - Value cannot be null. Parameter name: cipherText

HI,

We are trying to setup an integration between DW and NAV, but get this error when we are calling the service: "Value cannot be null.
Parameter name: cipherText".

We are using DynamicwebConnectorService - 1.0.0.5 and it should be set up ok. including the windows service on the server at the customer.

We can call the service in a browser and get the default "DynamicwebService Service" responsepage.

Using the testapp we do get the expected response when using the "NavService Test"-tab.

But using the "Dynamicwebservice Test"-tab, we get the error, the same happens when trying to test from the site.

Digging aroung i can see the error is thrown when  the service tries to decrypt the requst-message, so it looks a bit like that, for some reason, the request-message gets stripped before it hits the connector.

There is no proxy-server infront of the connector, and there should not be anything in the firewall that should block the request.

the shared secret is also ok, as we get another error if we try to change it.

And as we can connect with the  "NavService Test", the other settings should be ok.

Does anybody have had this problem too, and know what to do.

I have made quite a few of this integrations before, and have never run into this problem before.

Thanks

Regards

Kenneth

Hi Kenneth,

Have you installed the right .net version? And have you installed the right service 32-bit vs. 64-bit?

Best regards, Anders

Hi.

There is the right .net frameworks on the server, that i have gotten checked.

I'll have to check what version og the connector they have installed.

Thanks

Best regards, Kenneth

Hmmm

Now they have tried to installe the 64-bit version og the connector, and we get the same error.

the request is: <GetEcomData><tables><Products type="all"/></tables></GetEcomData>

the response is:

"Value cannot be null.
Parameter name: cipherText"

Any other ideas ??

 

Best regards, Kenneth

Hi Kenneth,
this error is caused by passing an empty request xml to the Dynamicweb service.
Could you try to double check you are not sending an empty requests?

Hi Kenneth,
another situation when it can throw the same error message is empty response returned from the ERP which is then is tried to be decrypted back on the Dynamicweb side using shared secret.
So could you check the ERP response is not empty string? If it is empty could you try to check with empty shared secret?

hi

The response from the ERP is not empty.

If we in the DynamicwebConnectorServiceTestApp tries to make a request in the "NavService Test"-tab.
We do get a valid response.

Hi Kenneth,
could you check the Dynamciweb service config file?
<appSettings> ConnectorType should be set to the Nav connector type, "TestMode" to false, and also check the NavConnector section has the correct NavEndpoint?

It seems like you have misspelled: NavConnectorAddInn - you have a "n" to much in this: NavConnectorAddInn.NavConnector

Hi,

 

I also have the same problem but still having the error.

Here's the configuration file.

<NavConnector>
    <add key="UserName" value="user" />
    <add key="Password" value="pass />
    <add key="Domain" value="localhost" />
    <add key="NavEndpoint" value="http://localhost:11047/DynamicsNAV110/WS/CRONUS%20International%20Ltd./Codeunit/DWWebService" />   
    <!-- Set IgnoreCertificateWarnings to true for https endpoints using self-signed or untrusted certificates. Useful for testing. Should be avoided in production. -->
    <add key="IgnoreCertificateWarnings" value="True"/>
    <!-- Valid options for ClientCredentialType are: Default, Ntlm, Windows, Basic -->
    <add key="ClientCredentialType" value="Default"/> <!-- I also tried Ntlm, Windows and Basic here but got the same issue-->
  </NavConnector>
  <appSettings>
    <add key="ServiceName" value="DynamicwebService"/>
    <add key="testMode" value="False"/>
    <add key="TestOutputFile" value="c:\DW9Projects\exportContent.xml"/>
    <add key="Secret" value="secretkey"/>
    <add key="DebugInfo" value="True"/>
    <add key="WebserviceURI" value="http://localhost:8090/DynamicwebService"/>
    <add key="ErpConnectorType" value="NavConnectorAddIn.NavConnector"/> 

 

Can someone help me?

Using the test app, under NavService Test I retrieved the xml data. But on the DynamicwebService Test tab here's the response.

Value cannot be null.
Parameter name: plainText

 

 

Thanks

Hi Suzette,
probably you could have the same problem but with using wrong config file key names: "ErpConnectorType" was used in the old DynamicwebConnector service project(1.0.0.*).
But if you are using the DynamicwebConnector service 2.0.0.* you need to use "ConnectorType" instead.

Hi Suzette,
It is on this page in the bottom of the Integration downloads list starting with an "Intregration v2" prefix.
What version have you donwloaded and are you using?
Could you check you have the NavConnectorAddIn.dll in the folder where you have setup/registered your Dynamicweb service?
Could you also check if there is any error information in the Winodws event viewer logs(after you are requesting data from the Dynamicweb service):
Start Winodws event viewer and open: Windows Logs -> Application and Application and services logs -> DynamicwebService?

Hello Dmitriy,

 

Yes both the Test app and the Dynamicweb Service have the NavConnectorAddIn.dll on their folders.

I checked the event viewer log, there's no DynamicwebService

Hello Dmitriy,

 

Please also update the documentation part of the integration if the old connector test tool is not working anymore. 

 

 

 

Thanks!

There is no need to update the documentation as the older connector tools are working as they were before.

Hi Dmitriy,

This part of the documentation it is stated the still using the "ERPConnectorType" instead you said you use the "ConnectorType".

 

Please see attached file for the screenshot.

Hi Suzette,
The documentation is already there. The article you link to describes how to work with Integration Framework V1(DynamicwebConnector service (1.0.0.*)), not the V2.
This article deals with the connector on Integration Framework V2: https://doc.dynamicweb.com/documentation-9/integration/integration-framework-2/testtool-connector-service

Here's the configuration file.

    <add key="IgnoreCertificateWarnings" value="True"/>
    <!-- Valid options for ClientCredentialType are: Default, Ntlm, Windows, Basic -->
    <add key="ClientCredentialType" value="Default"/> <!-- I also tried Ntlm, Windows and Basic here but got the same issue-->
  </NavConnector>

Hi Suzette,
I've not received any answer from you on mine question regarding the log information. So I am copying it here once more:
Could you check what information do you have in the Winodws event viewer logs(after you are requesting data from the DynamicwebService Test tab/Dynamicweb service):
Start Winodws event viewer on the server where Dynamicweb service is registered and open: Windows Logs -> Application
Do you see any information like that with a Source "Dynamicweb service?:


If yes: look in the event error information

Hi Suzette,
the log shows that your Dynamicweb service can not be started.
Could you also let me know the details of the logs found in the MyNewLog section?

Ok, when you make a request to the service, what information is shown in the event viewer logs?
Are there other errors, or still the same one:"Service cannot be started. The service process could not connect to the service controller"?
What is written to the MyNewLog section?

Can you send me your two config files:
1) the one you have at running the tester tool
2) the one you have in the folder where you have registered the DynamicwebService Windows service
to my email: dbe@dynamicweb-cms.com?

You need to fix your DynamicwebService config file:
<appSettings>
    <add key="ServiceName" value="DynamicwebService" />
    <add key="testMode" value="True" />
    <add key="TestOutputFile" value="c:\DW9Projects\exportContent.xml" />
    <add key="Secret" value="test" />
    <add key="DebugInfo" value="True"/>
    <add key="WebserviceURI" value="http://localhost:8090/DynamicwebService"/>
    <add key="ErpConnectorType" value="NavConnectorAddInn.NavConnector"/>
  </appSettings>
Set:

    <add key="testMode" value="False" />
