Mysterious type conversion error when trying to refresh in PBI service
A dataset won't refresh on account of a type conversion error which isn't present on refresh within Desktop. No information is given within the error other than which table it is occurring in. This table has multiple appends so I checked to see if there were any possible datatype issues there. I narrowed it down to a particular append, but cannot find where the issue lies. This included trying to fix any possible issues in the date fields - which are formatted exactly the same and continue to throw the error even when converted to a text type prior to being appended. All other appends execute and refresh successfully.

We saw the same and raised a ticket. All we got was a shrug. The issue is aggravated by the fact that the error message conveniently forgets to mention which column caused the error.

Got an update. I may have FINALLY seen some progress here after meeting with Microsoft support several times a week for nearly 2 months. It's been escalated to the dev team (or at least so I'm told) and they're expected to roll out a fix within the next two update cycles, so... fingers crossed.
Managed to get a ticket up (which was itself a bit of a process given that the GD ticket submit button was broken the first time I tried 😠), so we'll see what happens. I'll let you know if anything worthwhile comes out of the process.
