Json Extractor and Extension cannot be used simultaneously？

[PopBing]

Summary

I have a scenario where I need to use the Json extractor to extract interface parameters in the post request. Extension reads the authentication information obtained after parsing the interface token in the AsyncRequireAuthorizationLayer, prompting a compilation error

After changing to the Query extractor, it can mutate normally.

After reading the source code, it was found that Extension did not implement the FromRequest trait.

Is it possible to support this usage? Thanks in advance!

The Json extractor must be used last. See The order of extractors for why, and Debugging handler type errors for future reference.

The issue has been resolved, thank you very much.
