Insert Index Column in Power Query shows in preview but always just says "Failed" when refreshing the data

Customer Insights

We needed a unique column which was not in the data set, so we used the "Add Column" using the "Index 1" type (Index starting a 1 and incrementing by 1).

The new column showed in preview correctly, and after hitting "Next", the query validated, but during the refresh after a few minutes, it just said "Failed".

No error code or diagnostics of any kind.

    Hi there,

    It might be your field name.

    Customer Insights does not accept any spaces or characters other than letters, numerals or underscores.

    So try "Index_1".

    I found the resolution to the issue. It was not actually failing on the Index_1, it was failing for Non-unique columns in CI. Just interesting that it did not notice the non-unique columns until after I added the Index_1 to the column list. Once I resolved the non-unique column issue, the Index_1 works now.
