Internal ticket ID: AP-24482Summary: DB Loader fails when connected to Google BigQuey with No FileSystem for scheme “file”Fix version(s): 5.4.5, 5.5.1Other related topic(s):
Hi KNIME Team,
I’m encountering an issue with the DB Loader node when uploading data to a Google BigQuery table using Parquet format. This problem started occurring only after upgrading to version 5.4.4. In earlier versions (e.g., 5.4.3 and prior), the exact same workflow and configuration worked perfectly.
The error message I’m receiving is:
Execute failed: No FileSystem for scheme “file”
This seems to indicate a problem related to how file systems are handled internally in this version whe…
When attempting to create a table and load data into BigQuery using the DB Loader node, the Loader node executes to 10% after which I get an error: “Execute Failed: No Filesystem for scheme “file””. On the other hand, when using the DB Writer node, my table gets created and data writes to the table, albeit extremely slowly. Any insite into what is causing this error in this node?
