Hello everyone! I'm new to Meltano. I working in a custom tap and I have been trying to create a pipeline with my custom tap and target-csv. I debugged my pipeline, doesn't get an error but the target don't create the corresponding CSV file. How can I check what is happen with the data on my custom tap? I'm not sure how it's sends the data to the pipeline or how do it expect or should the information arrive to the target-csv for it to work?

Checkout the troubleshooting docs for some tips! https://docs.meltano.com/guide/troubleshooting

I saw the guide before and tried some things like the log-level-debug and invoke command, but is the same, doesn't have an error. So, where can I learn about how it's sends the data to the pipeline or how do it expect or should the information arrive to the target-csv to know what am I doing wrong?

Maybe the singer spec docs would be helpful https://hub.meltano.com/singer/spec

If you run

meltano invoke tap-x

or just directly run your tap outside of meltano while developing it you should see Singer messages print to standard out. Its possible that the tap isnt emitting actual records for some reason, it would be good to inspect the raw output to start

I added some print messages with LOGGER and I could see when I use the meltano invoke or meltano run. Also with these prints I can see the data. So how can I inspect the raw output?

The output would show up in your stdout if it was being sent properly. Do you see SCHEMA or STATE messages?

Not any of those messages. I reading the singer spec doc and I'm seeing that I do not receive any of those messages.
