Hey @MerryMarketing,
Thanks for sharing the HAR file. The error showing INTERNAL_ERROR with shouldRetry: false can sometimes point to a portal-level permissions or account configuration issue rather than something on your end.
If you’re following the steps from @evaldas, are you able to confirm your portal is enrolled in this beta here? Additionally, are you able to confirm if you’re an Admin in the portal?
Thanks for your help so far, @evaldas!
Best,
Sam
