Connection sync failed when saving parquet from mongodb to s3

Hi @alafanechere ,
Once the same process was carried out in ubuntu, the permission problem was solved. This time there was another error.
tech.allegro.schema.json2avro.converter.AvroConversionException: Failed to convert JSON to Avro: Could not evaluate union, field win is expected to be one of these: NULL, STRING. If this is a complex type, check if offending field: win adheres to schema.
It seems to be an error caused by the convert.
I will attach the log as a new topic and upload it again.
