Any idea what it might be?

Thank you,

Can we see the entire stack?

Hi Nicolai,

This is the entire message I see in the interface in Monitoring.
Should I look elsewhere?

Thank you,

You can probably find it in the log folder.

But as you can see it seems like you have some bad data in a product selector somewhere, maybe a discount?

Hi Nicolai,

I don't know where to find it in the log.

Is there any way I can figure out what product selector is causing this issue?

I have a lot of these messages and we don't have custom discounts.
