Hi kadirkkkk ,

Thanks for reaching out to the Microsoft fabric community forum.

Thanks for flagging this. After further analysis, this is expected behavior in Power BI when using Template Apps.

In external tenants (where the app is installed), Power BI suppresses custom error messages created with error.record() or try ... otherwise error logic. This is likely due to privacy and security constraints in multi-tenant environments

let
result = try MyStep,
output = if result[HasError] then
[Status = "Error", Message = "Custom error message here"]
else
result[Value]
in
output

This ensures your message will appear consistently across tenants and within the installed app.
