[Migrated] Multiple query fields with same name only returning last value

jneves commented 3 years ago

Originally from: https://github.com/Miserlou/Zappa/issues/1508 by seandavi

Context

I have a Flask/Flask-RESTPlus (very simple) that has a query parameter, fields, that is described as:

parser = api.parser()
parser.add_argument('q', type=str,
                    help='A [lucene-syntax](https://lucene.apache.org/core/2_9_4/queryparsersyntax.html) query',
                    default='*')
parser.add_argument('from', type=int, help='The starting record to return (for pagination), zero-based', default=0)
parser.add_argument('size', type=int, help='The number of records to return (for pagination)', default=10)
parser.add_argument('fields', help="fields to include in output. See 'mapping' endpoints for list of available fields", action='append')

Expected Behavior

When running locally and querying with:

http://localhost:5000/....fields=a&fields=b...

My code sees the fields as an array of fields.

Actual Behavior

When running on the API endpoint after deploying (and updating), I see only the last value of the fields parameter.

Possible Fix

Steps to Reproduce

The issue only manifests itself once deployed, not in the "local" environment.
