NetworkControlError/NetworkTimeoutError "feature not supported" in logs

[bfrederix]

Question
I'm using the Go library and running Tus in Google Cloud Run. I'm able to upload files fine using Uppy+Tus but I keep seeing this type of error in the logs:
WARN NetworkControlError/NetworkTimeoutError for PATCH request with error "feature not supported"

I'm not sure why these are happening. Maybe you can see from my code? I tried the configurations you see on line 122 but those actually made Tus stop working all together. Is there something I'm missing?

I know the NewHandler is probably recommended over the NewUnroutedHandler and handles everything, but I want to use the datadog muxtrace for observability purposes.

Here is the code for reference:

Thank you.

Setup details

• Operating System: Google Cloud Run
• Used tusd version: v2.2.2
• Used tusd data storage: Google Cloud Storage
• Used tusd configuration: You can see the config in the gist above (running the Go library)
• Used tus client library: tusd (Golang imported library)

There was a similar question a few weeks ago that should help you understand what this error means: #1100

What I assume is that some middleware or router is wrapping the ResponseWriter in a way that does not support the ResponseController, which is necessary for tusd to properly handle timeouts. The corresponding middleware should then be adjusted as mentioned in #1100 (comment).

I hope this helps! Since this is already the second time someone ran into this, we should add this to the documentation somewhere.
