Hi all,
I keep running in to a refresh error for my XML file. Background: A user accidentally changed the authentication token in our data source to which the XML file is connected to. the token was changed back to the original, but since then, when the table refreshes automatically, we encounter this error code:
DataFormat.Error: Xml processing failed. Either the input is invalid or it isn't supported. (Internal error: Reference to undeclared entity 'nbsp'. Line 4, position 23.). . The exception was raised by the IDbCommand interface.
Things that temporarily fixes it was to create a new parameter with the authtoken and then reference the xml file via dax to the new parameter it worked for about 24h, but when the next scheduled refresh came through, it failed again. always the same error code.
Thanks in advance,
L
