TypeError: Cannot read properties of undefined (reading 'tokenType')

Hi there!

There is a bug in the page returned by the "embed_url" of a dashboard.

If you search for this function:

function isSaaSEmbedWithAADToken(config) {
  // Default token type is Aad (0)
  const tokenType = config.tokenType || 0;
  return (window.isSaasOrPaasEmbed === true) && (tokenType === 0);
}

You will see that there is one location where it is called without the required config parameter:

if (isSaaSEmbedWithAADToken() && config.settings && config.settings.personalBookmarksEnabled) {
  url += "&defaultBookmarkEnabled=true";
}

Which causes this exception:

TypeError: Cannot read properties of undefined (reading 'tokenType')
  at isSaaSEmbedWithAADToken (reportEmbed?reportId…d&uid=cslgcq:586:38)
  at getModelsAndExploration (reportEmbed?reportId…d&uid=cslgcq:696:17)
  at getModelsAndExplorationAndConceptualSchema (reportEmbed?reportId…3d&uid=cslgcq:840:9)
  at xhr.onreadystatechange (reportEmbed?reportId…d&uid=cslgcq:505:37)
  getModelsAndExploration @ reportEmbed?reportId…0%3d&uid=cslgcq:739

All this happens inside the page returned by the embed_url, so it happens regardless of my code or how I initialize the client library.

So this seems to be an internal bug of PowerBI. One that was introduced fairly recently, because this exception did not happen a couple of weeks ago.

Hi,

From my investigation, I have found that the powerbi embed works as expected in chrome version 94 and onwards but fails in older version than that. The above error appears in all versions of chrome but the reports show up fine in version 94 and onwards in spite of the error.
