Getting transient Null Exception when refreshing a data source
I keep getting the error below when I do a full refresh on my Power BI report. However, refreshing the data source individually works without any issue. OLE DB or ODBC error: [Expression.Error] ...
RezaAssadi hello,
do you have some dependency on some tables, or are you waiting for some query to finish before you get values for another one, that's the only thing I can think of.
I do have different references between different tables. However, that used to work just fine before and I am not entirely sure why it would only break if I refresh all Data Sources at once (and not when I just refresh this one data source). What's more challenging is that there are no error logs telling me which column has a null reference and where that null reference is. I verified the underlying query and confirmed none of the columns are null.
