I’ve built my own tap based on SDK. I have done a

poetry build

and a

poetry publish

to pypi. I created a separate repo and tried to install the tap via

meltano install

. I get the following output:

Installed loader 'target-jsonl'
Installed extractor 'tap-rest-api-msdk'
Installed 2/2 plugins
Expecting value: line 1 column 1 (char 0)

Can you try running with --log-level=debug?

here’s the stack trace:

The above exception was the direct cause of the following exception:

There may be multiple things going on here... Is this being published based on the config file here?: https://github.com/Widen/tap-rest-api/blob/master/pyproject.toml#L24 One thing to check is if the

executable

matches the CLI declaration.

.meltano/extractors/tap-rest-api-msdk/venv/bin/tap-rest-api

Just noticed that it doesn’t

Okay, thanks for confirming. That's probably the main issue you are running into.

thanks. I knew when I switched the name of the tap I was gonna get issues. on to the next error I guess …

Fair enough... yeah, this gets populated for you during cookie-cutter eval, but not obvious that it needs to change or be updated if the executable gets renamed.
