Null pointer exception when using macros in source GCS

[graypes]

I am using argument settings to populate as many settings in my pipeline as possible.  The pipeline consumes files from GCS, processes with Wrangler, and writes out to GCS and BigQuery.

I am able to use the macros everywhere EXCEPT in the source GCS.  If I try to set a macro for "format" or "schema", I get a null pointer exception error.  It is no problem in the sink GCS steps.  It definitely appears to be a bug.

Here is the relevant settings in my arguments JSON:

{

  "arguments": [

    {

      "name": "gcs.source.path",

      "value": "gs://org-usssa-dw-data-lake-dev/source/legacy/athleteAward.csv"

    },

    {

      "name": "gcs.source.format",

      "value": "delimited"

    },

    {

      "name": "gcs.source.delimiter",

      "value": "~"

    },

    {

      "name": "gcs.source.schema",

      "type": "schema",

      "value": [

        { "name": "mvp_id", "type": "int", "nullable": true },

        { "name": "player_id", "type": "int", "nullable": true },

        { "name": "tournament_id", "type": "int", "nullable": true },

        { "name": "mvp_name", "type": "string", "nullable": true },

        { "name": "StatureID", "type": "int", "nullable": true },

        { "name": "season_id", "type": "int", "nullable": true }

      ]

    },

  ]

}

It seems that it responds to publicly accessible objects. Can try setting your GCS in to public? For more information you can view the documentation here:

I created a new bucket and made it public.  I uploaded my arg settings files and pointed the data pipeline arg settings plugin to the new location.  I still get the same results.

Understand that the arg settings were working fine when the bucket wasn't public.  The problem is only when attempting to use arguments/macros on the GCS source, and only on the "format" and "schema".
