Hi @Hussam_AlJabri
Thanks for the video, I tried to recreate your workflow (see attached gif) but unfortunately I cannot reproduce the issue you saw. If it is possible could you please share more info with us, so that I can keep digging. Or it would be easier to contact Esri Support and work with an analyst, and they will be able to diagnose further and work with you on this.
Here are some questions that I have:
1. I guess your URL of the data page is created by joining few variables. To eliminate the affect of dashboard, could you please try open that URL in the web browser directly? If the error appears without dashboard, could you please let me know what is included in the URL?
2. I guess you embed a dashboard in another dashboard, and the data page is opened to replace the inner dashboard. I can only achieve this by modifying the code in the browser developer tool, since the dashboard indicator always open the page in a new tab. Could you please let me know how to open that page in the frame?
Thanks,
Ruth
