Does log_by_lua_* run if the response status != 2xx?

Sorry, I should have also specified I am using the docker file: openresty/openresty:1.13.6.2-alpine

Does log_by_lua_* run if the response status != 2xx?

Hello everyone,

]Even with the most basic example:

location = /wtf {
log_by_lua_block {
ngx.log( ngx.ERR, "hello from log_by_lua_block" )
}
return 404;
}

nothing gets logged, same with 5xx, and also if I do it using ngx.status - but if I return 2xx it logs as you'd imagine.

Is that the expected behaviour? Can't find anything in the docs, maybe it's just standard nginx phase stuff where you only get to log phase on a "successful" request?

Thanks!

Igor

There must be more going on in your configuration, this example works for me.

Maybe you have some error_page definitions? They are separate locations that use internal redirects, so log phase happens in location that handles these documents, not in the location that is initially matched.

Thanks Piotr, I'll have a look into that. I found another way to do what I was trying to do but this is useful info anyhow. Appreciate it!
