Expression.Error: The column 'P6 ID' of the table wasn't found

[smjzahid]

I have a dataflow, which was refreshing successfully, However, I have started receiving this error and the refreshing is failing for one of the tables named (Projects) in the dataflow. Other tables do get refreshed successfully. (see below) the downloaded error report from the PBI Service

the Advanced Editor has do not show any column named P6 ID

How do I trace the cause for this error. The connector used for this query is the Web.Json

Hi @smjzahid ,

You can try to add a error handling steps in your m-query.  

ErrorHandling = try #"Expanded project 1" otherwise null
