This refresh error is weird, because the function causing the error doesn't feature in any of the M code !
(At least, not in the M code in the desktop pbix file that designed this report.)
Any ideas?
@TomTomTom - Looks like you are trying to add an Index column in that code. For some reason, I recall this exact error happening to someone else when they were trying to add an Index column. Can you post your Advanced Editor code?
If I recall, dropping the newly added 5th parameter should fix it. So, drop the ", number" part when adding the index.
