@mattkab correct. it doesn’t reply , so the front end is waiting. it checks the loaded status, and waits til that happens which will never occur. the node helper could log the status( it’s not 200) and any error reported in the API callback. to help w this debugging. most of the modules have limited to no error recovery

@ghiesseldorf Thanks a lot, I had the same error after the last update and it fixed it for me
