Complete build log showing all packages used and steps taken to achieve the failed result.

The common theme is that the expected values include header Transfer-Encoding, but the observed data have transfer-encoding (notice capitalization). And yes, this patch makes the test suite pass for me.

I am not sure what could be the cause: all libraries seem to be at least in the allowed versions.

With uvicorn 0.18 the headers are lowercase again.

I don't see any changes on uvicorn related to this... 🤔

[bnavigator]

Yet it makes a difference: with uvicorn 0.17 you get the failures as shown above; with 0.18.2, you don't.
