DataSource.Error: OData: Invalid JSON. Unexpected end of input was found in JSON content.

Hi

We have used PowerBI integrated with Business Central for years without issues with the same dashboards that have been changed recently. This morning, they stopped working, and it seems like the error already starts when trying to access a specific dataset "Cust_LedgerEntries" from Microsoft Business Central (see below). How can this be, and what can be done to fix it?

We use multiple datasets and all others load normally. It is already when trying to "get data" or in the "Navigation" step that the error starts and not in any other applied steps (see below).
