Can a request returning a file cause issues? #458

Closed bptouchette closed 1 month ago

bptouchette commented 2 months ago

I have an API where if I call a specific URI it will return a file that my browser can download. If I use the URI with "localhost:8080" for exemple, the URI works fine and the browser downloads the file. If I use the devtunnel uri "test-8080.use.devtunnels.ms" for exemple, then I get a 502 error everytime and nothing happens.

I can see on my server that the call is being made properly and that my server returns a 200 with the file in question but for some reason the devtunnel is returning a 502.

Is devtunnel able to support request where the response has a content-type specific to a file? Exemple image/png or application/pdf? It seems to work fine if the response contains JSON.

I'd recommend reviewing these limits - https://aka.ms/devtunnels/limits. If you don't believe you're hitting any of those limits, with the request id and timestamp, we may be able to better track down the cause of the 502.

Closing this as stale but please comment to clarify your use case if you continue to see an issue.
