> It's possible for fastavro to fail to correctly load its cython implementation of the Writer class in which case it will silently fall back to a pure python implementation. If this happens there's no outward indication, but line 621 in io/avroio.py will fail because writer.fo is only present on the cython implementation.
> To reproduce you can modify fastavro's write.py to only use its fallback:
> {code}
> #from . import _write
> from . import _write_py as _write
> {code}
> And then run a workflow that sinks to WriteToAvro(use_fastavro=True).
