Compilation error: invalid conversion from 'const AsyncWebHeader*' to 'AsyncWebHeader*' [-fpermissive]

[kingnoob1377]

I had errors compiling pidkiln.
I had other several errors compiling, but I was able to get through them somehow.
This thing I have no idea.

how can I complete my compilation?

compilation terminal output
log.txt

installed libraries

My sketch
PIDKiln.zip

Hi, I would guess there are some braking changes both in esp32 Arduino framework and asyncwebserver. You can try to compile it with older versions. I'll also probably update/fix the code, but can't say now when exactly :)
