HTTP 2.0 Throws KeyError rather than the internal exception thrown in the thread
The starting point for issues should usually be a discussion...
https://github.com/encode/httpx/discussions
Possible bugs may be raised as a "Potential Issue" discussion, feature requests may be raised as an "Ideas" discussion. We can then determine if the discussion needs to be escalated into an "Issue" or not.
This will help us ensure that the "Issues" list properly reflects ongoing or needed work on the project.
- [ ] Initially raised as discussion #...
We are running into a number of HTTP 2.0 protocol errors with a remote supplier. We have seen two exceptions that are raised internally, but when it makes it to the calling routine, it turns into a KeyError exception. Here are the exceptions:
EXCEPTION #1
