For a data flow, I use the power query source for getting json data in a table format.
That works like a charm if i don't change the folder path on the connection manager. If I change the folder only in the connection manager to another folder, there always is an error "Credentials are required to connect to the Folder source: 'old path to folder'".
That's probably because in the power query is still the old path. e.g. the query looks like this:
let
Source = Folder.Files("D:\StageTransfer\MedicationBilling\Data")
....
Probably I could do a workaround, if I change the query mode from "single query" to "single query from variable", but then, I have to escape every quotation mark in the query, making the query unmaintainable.
Does anybody have the same problem and has another solution for that?
