Index Failure on Object Type because of missing column

Hi all -

I have an object type that built with the correct columns, but is not populated with any objects. I’m getting the message that the index has failed, so upon investigation, the changelog stage is failing with the message “Cannot find column [ X ] which is mapped to property [RID] in the schema.”

Column X exists in both the dataset used to create the object type and the object schema. It’s also the same datatype (string). Any advice on how to proceed from here?

Thanks in advance!

If you look at the Properties tab of the object configuration page, are there any unmapped columns if you open up the dataset view (tray at the bottom of your screen)?
