Meltano

Hi Team, New to Meltano, Requesting for a help to understand this error "[*error*  ] *Block run completed.*       block_type=ExtractLoadBlocks err=RunnerError('Loader failed') exit_codes={&lt;PluginType.LOADERS: 'loaders'&gt;: 1} set_number=0 success=False" and how do we troubleshoot with  Meltano error's ?

```meltano run tap-postgres target-bigquery```

gets me to the above error.,  for pg i am able to check my config using '''meltano config target-postgres test'''

but for target-bigquery how do we test if my connection is right ? and the connector is able to communicate with my BQ access . ?

I haven't used bigquery before with meltano - but I would try meltano invoke with your big query connection

<https://docs.meltano.com/reference/command-line-interface/#invoke>

so something like
```meltano invoke --log-level=debug target-bigquery```

Yeah, a good general of debugging pipelines is to:
1. Direct the tap output to a file, e.g. `meltano invoke my-tap &gt; singer.jsonl`
2. Pass the contents of the file to the target, `cat singer.jsonl | meltano invoke my-target` 
3. Inspect the contents of `singer.jsonl` if the above fails
