Try the branch
current-dev, it might work.@ADD-SP commented on GitHub (Dec 31, 2021):
Solved?
@ehdud8451 commented on GitHub (Dec 31, 2021):
I'm sorry for the late response.
An error was found in connection with this, but I'll check if this is an error related to ngx_waf and reply again.

I'm a beginner. I can't check why this error appears. What can I do?
@ADD-SP commented on GitHub (Dec 31, 2021):
It looks like there are some compatibility issues with pcre2, I'll let you know when I fix it.
@ADD-SP commented on GitHub (Jan 1, 2022):
Retry the branch
