Refill Buffer Error while refreshing a table
The power bi has tables connected to Databricks SQL Server
While refreshing 1 of the tables getting this error: OLE DB or ODBC error: [DataSource.Error] ODBC: ERROR [08S01] [Microsoft][Hardy] (115) Connection failed with error: Could not refill buffer
I have already tried to reduce the size of the output by reducing the date range in SQL Query, cleared cache. The only step applied in power query is converting text to date for a date column. This error has started occuring after I replaced a column with another in Query.
The query loads correctly in Databricks, the power query preview loads as well, the problem occurs only after "Close & Apply"
New to this forum, I have tried looking for solutions on Copilot, nothing helps if any ideas please let me know, I will be very grateful

Hi ShreyasMungad​ -I'd recommend first revert the column and test Close & Apply. Since the failure appeared immediately after the column replacement, that's the highest-value test. If it still fails, switch the Databricks connection to ADBC (Implementation="2.0"), because the error is occurring during the actual data transfer rather than SQL execution. Microsoft currently recommends testing ADBC for Databricks connections.

Hope this helps.
