raise CliError(str(err)) from err

meltano.cli.utils.CliError: Run invocation could not be completed as block failed: Loader failed

I got this error and over again, can anyone please help me with this error, I don't know what went wrong in my yaml file

You can try using debug mode https://docs.meltano.com/guide/integration#debug-mode to get more details on the exact error. Posting that log and your meltano.yml (minus any sensitive configs) could help for debugging
