Encountering an error trying to access a dashboard. Data Source error is being displayed. Looking at the developer tools I see an error saying the rest endpoint call failed to fetch data from origin (url that's included in our allow origin list) has been blocked by CORS policy. When others with similar roles log in they can access the data fine as well as when they log in as me.

Hi @IT_mnaa,

I would recommend posting this question on the ArcGIS Dashboards Question board for better visibility - https://community.esri.com/t5/arcgis-dashboards-questions/bd-p/arcgis-dashboards-questions.

Can you view the data outside of the dashboard? Or do you get the same error?

All the best,
Clio

I will post the question there. Thank you. I don't believe the data is displayed elsewhere to know if the data can be viewed outside the dashboard
