unexpected number in JSON at position X when running query for map vis

[tboulis]

We encountered an issue while fetching the underlying data of a map vis:

The issue is that the response of the looker api contains invalid JSON objects for the field users.approx_location which fails to be parsed using the typescript sdk.
I tested it on the API Explorer on the looker website and I saw that the data looks like this:

which obviously is not a valid object.

Is this a known issue and does it apply to all map vises or is it just an isolated issue that is related to the sample data for partner instances?

Edit

I tested both
GET /queries/49/run/json_bi
and
POST /queries/run/json_bi
and both returned the same bad data

Part of data:

This may be a looker API bug rather than a typescript sdk bug. Can you open the looker bug through the normal channels?

Thanks

I tried running a query via API Explorer for a location field and it seemed to work properly...

  "rows": [
    {
      "airports.map_location": {
        "value": [
          40.63,
          -73.77
        ]
      },

What is the data type of the field "users.approx_location"?

Hello @drstrangelooker thank you for looking into this.
It seems that it is of type location:
