Hello,

When attempting to transfer data from a Sharepoint Online List to a Dataverse table, I encountered this error:

Despite trying numerous methods to fix this error, including assigning different primary keys to select for, I still was met with this same screen no matter what. Any advice? Thanks!

I am trying to do the same thing and have the same message, I don't see how this answer helps.

There is no field "AttributeCollection" in either the source or the dataverse table.

If there is a field validation error, why can't it tell me which field is failing validation.

For me the source somehow had two fields differing only in case, i.e Id and ID. Removing one of these in the PowerQuery interface resolved the problem.
