The stack trace here doesn't seem to be anything to do with Minimal APIs - it's to do with MassTransit. What exception do you get if you temporarily remove your background service? It could be that one problem is causing another, but then that problem masks the original error, meaning it looks like you get a terrible error message.
from aspnetcore.
To clarify, the error message is indeed a result of using the [AsParameters] attribute incorrectly. The issue isn't related to MassTransit or other dependencies, as we encountered this problem in a nearly empty project as well.
The error message generated is over 300K characters, making it impractical to post in full here. It encompasses details from various components of our project, including MassTransit, Hangfire, MediatR, etc., leading to a convoluted stack trace.
Hereβs an example in a minimal setup:
Reproducible Example:
app.MapPost("err", ([AsParameters]List<IFormFile> files) => "OK");
Resulting Error:
crit: Microsoft.AspNetCore.Hosting.Diagnostics[6]
Application startup exception

We have spent more than an hour until we have found the error in our case.

Thanks - that looks like it contains enough information now for someone to look into.
