I'm getting an error using <https://github.com/z3z1ma/tap-mongodb>.

&gt;  2025-03-25T02:30:05.343188Z [error ] Block run completed. block_type=ExtractLoadBlocks err=RunnerError('Cannot start plugin tap-edgar-mongodb-v1: Separator is found, but chunk is longer than limit') exit_codes={} set_number=0 success=False
It's intermittent, but seems to be happening more frequently. The error seems similar to <https://github.com/z3z1ma/tap-mongodb/issues/5>.

Does anyone know how to fix this, or any workarounds?

Can you try bumping this value in your project?

<https://docs.meltano.com/reference/settings/#eltbuffer_size>

So, we had it at about 2GB for a long time. Yesterday I changed it back to the default. No difference.

Just tried with 200MB. Still problematic.

Do you get to see a `Inferred schema: ...` message from the tap?

No, I don't see that message. Here is a log from the tap:

I'm still getting the chunk error above. Any tips on how to troubleshoot this?

My first recommendation would be bumping <https://docs.meltano.com/reference/settings/#eltbuffer_size> from 2GB to a larger value, but that's already quite a large value. Perhaps invoke the tap in isolation, see if you get the same error, and inspect the Singer stream for messages or other output that could be problematic:
```meltano invoke tap-mongodb &gt; singer.jsonl```
