Hi team, I ran into another issue with one of my custom HTTP connectors and would be very thankful if you could help. When running the source-connector from the console using the following command, everything works fine:

docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/sample_files:/sample_files airbyte/<CUSTOM_SOURCE>:dev read --config /secrets/config.json --catalog /sample_files/configured_catalog.json

However, the Airbyte GUI throws the following error message and the sync fails (I tried it with both S3 and local json destinations):

Hi. This is the error:

"java.net.URI.toString()" because "currentUri" is null

check the logic

Hi Eli, thanks for your reply. I have seen that this is the error and I believe that this is Airbyte logic. I do not quite understand where the error stems from, especially since the Python source connector runs perfectly when executed in the terminal.

this requires more debugging then. What connector are you using? what did you change?
