Creating reports and dashboards | Stimulsoft community forum

Hello,

You are welcome.

Dear Lech Kulikowski

I have upgrade to vs2026 and Wisej 4 and using .Net Core 10.

I am trying create tiny program to test Stimulsoft report using Html + simulsoft JS.
but i always get error
"stimulsoft.reports.js:28 Failed to load resource: the server responded with a status of 404 (Not Found)"

and
"stimulsoft.reports.js:28 File not Found ("Report/Report1.mrt") showError @ stimulsoft.reports.js:28"

In Startup.cs i had add code "app.UseFileServer();"

Is there something that i had missing?

Thanks

Hello,

Please send your project for analysis.

Thank you.

Dear Lech Kulikowski

This the project

Thank you

Hello,

You need to add a custom MIME mapping for .mrt so ASP.NET Core serves the report template as a static file instead of returning 404 for an unknown content type.

Thank you.
