Is uploading text files (html, json, yaml...) supported?

Hi, I was trying to use miniserve to upload text files (specifically .txt and .yaml) and kept receiving Request did not meet this resource's requirements. error (http error 405). Looking at the help it seems only certain media types (audio, video, image) are supported; is my understanding correct?

I used curl -vF "@./myfile.txt" https://myserverurl/upload\?path=\/ (miniserve uses TLS, is listening on port 443, and the upload folder is the same as its the serving folder).

The last part of http response (the error part) is:

We are completely uploaded and fine Connection state changed (MAX_CONCURRENT_STREAMS == 4294967295)! < HTTP/2 405 < content-length: 50 < content-type: text/plain; charset=utf-8 < date: Sun, 05 Feb 2023 20:04:46 GMT < Connection #0 to host myserverurl left intact Request did not meet this resource's requirements

Thanks for your insight.
