Power BI CustomData not being passed to report

[gotters]

The ability to pass a customdata string field into a token request is now available for Power BI. Apparently it should be available in the dataset itself via Dax filter methods ie using a dax filter that looks like this

[State] = CUSTOMDATA()

I have followed all the available online instructions but the customdata that I am passing never seems to land in the report and I cannot figure out what I am doing wrong. I know the other parameters that I am passing such as username, datasets and roles are all working as expected but customdata just does not seem to work.

Is anyone able to advise what I might be missing? It never seems to come through. Any help would be appreciated. See screenshots below for what how I have implemented it. Thanks

Here is an example of the token request I am making 

Here is an example of the dax filter I created that is consuming the custom data 

I also tried adding the CustomData as a measure just to see it in the report (without applying any filtering)

Hi @gotters ,

Did you specify the master user a member of the role(s) you created. If no role(s) are specified, then all the roles the master user is a member of are used for RLS evaluation.

For more information on how to use CustomData() please refer to the following article.

Thanks for your reply. Yes we did make sure that the relevant master user was assigned to the role - but still had no luck getting it to work.
