Feed error when using Products.query

Hi guys,

I have a feed (standard Rapido) and I want to use Product.query instead of [Channel] PartnersEurope.query.

With the PIM query, the feed renders products but as soon as I change it to the Products.query I get a nasty error:

<Error>

</Error>

It seems to be related somehow with the Facets but even removing the facest would not solve the issue.

What am I doing wrong?

Thank you,
Adrian

It seems like a field mismatch issue. Maybe the same facet twice or something.

The product.query also uses macros and contexts that might not be working in the context of a feed.

Hi Nicolai,

I have tried removing all facets and I got the same error.

Macros can be a good candidate for this error.

Thank you, I will explore this avenue.

Facets are not on the query it self but in a seperate file.

Maybe a field is twice in the query...?

Hi Nicolai,

The query works very well for listing products in the product catalog.

Only when I am trying to use it for a Channel Feed throws that error.
