filter method getFieldAsync does return 401 on super store example

[LingVuDev]

Description

I have faced an issue where I wanted to get the field that was used for a filter. For this I found in the API reference this method getFieldAsync(). But instead of returning the field object, I always get unauthorized response, even though everything else from the API does work.

What I am using

Workbook: SuperStore - Shipping

My implementation

export async function getColumnRoles(worksheet: Worksheet): void {
  let metaInfo: any = {};
  const filters = await worksheet.getFiltersAsync();
  console.log(filters);
  // This gives me the error 
  console.log(await filters[0].getFieldAsync());
}

Request (simplified)

Request URL: [...]/w/Superstore/v/Shipping/sessions/A3093F7D1A1D4B409E9D8146FC983557-0:0/commands/tabdoc/get-datasource-pres-model
Request Method: POST
Status Code: 401 
Remote Address: [...]
Referrer Policy: strict-origin-when-cross-origin

My goal in the end is to find out whether the filter is assigned to a field which is a dimension or measure

Hello @LingVuDev
We have recently found and fixed an issue with Filter.getFieldAsync(). It will be fixed in our upcoming 1.5 version of the extension library (coming in Q2). Meanwhile, the only work-around would be to use Filter.fieldId, and look up the field in DataSource.fields. From that field, you can get the role.

Still getting a 401 on the latest extension version 1.5.0. I am using exactly this code snippet:

const worksheets = await tableau.extensions.dashboardContent.dashboard.worksheets.forEach(
    async (worksheet: Worksheet) => {
      const filters = await worksheet.getFiltersAsync();
      filters.forEach(async (filter) => {
        const field = await filter.getFieldAsync();
        console.log(field);
      })
    },
  );

Hello,

I have the same issue and I cannot use your workaround @johnDance because what I want is to retrieve the datasource from the field object.
Indeed, using Worksheet.getDatasourcesAsync() is way too long to execute when I just want to retrieve one precise datasource name.

@LingVuDev
I am sorry for the delay. We converted to a new mail client, and messages got buried.

We have duplicated the issue on server. It will be fixed in the October maintenance releases of Tableau server.

Thanks for your patience.

@LingVuDev
Actually... September maintenance releases. It should be fixed in 2020.4.9, 2021.1.6, 2021.2.3, 2021.3.1, and online
Thanks again,
John

There was a security update to 2021.3, so the maintenance releases that include this fix are now:
2020.4.9, 2021.1.6, 2021.2.3, 2021.3.2, and online

Closing as fixed.
