Null nested fields in Google BigQuery

Question

I'm trying to upload a json file to BigQuery contaning a nested field which is null but it's not accepting.

I tried a lot of different syntax but I always got the error: File: 0 / Offset:0 / Line:1 / Column:410, missing required field(s)

I tried to sent the value as many different values listed below and even ommiting it... "quotas": [] "quotas": null "quotas": "null" etc...

The schema definition... [..] "name": "quotas", "type": "record", "mode": "repeated", "fields":[
{ "name": "service", "type": "string", "mode": "nullable" }, [..] ] [..] [..] "name": "quotas", "type": "record", "mode": "repeated", "fields":[
{ "name": "service", "type": "string", "mode": "nullable" }, [..] ] [..]

Answer 1

From what I can tell in the logs for the import worker for that job, the line in question is missing a required field (the field name starts with "msi"). The line is otherwise well-formatted from what I can tell. I've filed a bug that BigQuery should give the name of the required field or fields that are missing to make this easier to debug in the future.
