I got this error today which I cannot really make sense off - it is just pulling items (we have several other flows going in both sandboxes and prod) but returns this error:

Are you sure it isn’t “inventory part” as the record type?

"Item" is not a valid record type. It's either inventoryitem, kititem, etc. as used in the script. I believe the same applies here.

yea its a pre-defined list though but I asked Celigo support - it is strange in any case, there is a record called service which works fine, and that pulls service items
