"Null check operator used on a null value" on "ServerHandler_.sendTrailers/ServerHandler_._sendError"

Hi thanks for the library! However I see NPE errors when using 3.0.3.

Full error log:

when using 3.0.3

Is this a typo? Latest version is 3.0.2, and that's also the version used in master branch.

I briefly looked at the code and from the stack trace you shared it seems like you're using an older version. Could you try with the latest version?

Oh seems like a typo. I will try the latest. Thanks!
