How do you implement Custom Visual Capability keepAllMetadataColumns?

[Anonymous]

Per documentation I added the following to capabilities.json:

"keepAllMetadataColumns": {
    "type": "boolean",
    "description": "Indicates that visual is going to receive all metadata columns, no matter what the active projections are"
}

I got this error running pbiviz start:

        error should be boolean .keepAllMetadataColumns

There's got to be something more to adding this feature? 

Any help would be appreciated.

Thanks

Hi  @Anonymous ,

If you need to customize the pbiviz file, you can refer to the following link, generally we do not recommend modifying the pbiviz file locally.

I see the key is not to paste in what is in the documentation, but rather...

"keepAllMetadataColumns": true

...which works.  The documentation should not be taken literal.
