This ticket duplicates your query listed in support ticket ID 1049478 and I would like to ask you to continue the communication in the other thread.
Though I will share my answer in this public thread hoping someone could benefit from it. Please refer to the attached screenshot and delete all attributes - Id, Index, Name. Check the baseURL and whether there is any dynamic part in it - if any, please delete it and leave the static part only.
If the frame is again not located that way please try to delete the URL at all and give it a try. Please let me know of the results once you have any.
Please refer to your other thread in case of any further assistance required. Thank you!
