Have you tried the fix on the below link? 
https://www.reddit.com/r/PowerBI/comments/1f7yadg/data_conversion_error_on_refresh/

We encountered the same error and by adjusting the 4th parameter on the API call, the problem went away

Before:
Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, null)

After:
Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, [UseReadOnlyReplica = null])

It works!

Thanks @usbocajuniors

This is not working for me
Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, [UseReadOnlyReplica = null])

Update: 

It's working. I was doing something wrong. 🙂

Hi to everyone,

any updates?

If I've understood correctly, actually the possible solution would be to change manually the Power Query code (M) as follow:

Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, null)

Replace with:

Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, [UseReadOnlyReplica = null])

I did a test with a new report (pbix file), and by default the M code for this connector is still the first one (so by default an incorrect code is given). I hope that there will be a solution to avoid having to change the code manually each time in new and already published reports.

Thank you for your help.

Hey,

is there any ETA for the fix? I understand there is workaround, but I hope this bug will not force everyone in the community to fix all the endpoints...

Hi all , 

Microsoft Fabric Support and Status | Microsoft Fabric

According to feedback on Microsoft Fabric support, the issue will have a fix deployed by the Mid to late September.
The current solution is: Customers will need to manually modify the query in the Advanced Editor by adding a record as the last parameter. Change the query from: Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, null) to: Dynamics365BusinessCentral.ApiContentsWithOptions(null, null, null, [UseReadOnlyReplica = true])
