CSRF: Disable error log?

[uptownhr]

Is there a way to disable the error logging when a CSRF token missing is triggered? I guess someone is constantly trying to take advantage of my server my logs are flooded with

Not sure if this issue is still relevant, but seems like either the express default error handling or a custom error handling is generating this log.

If it is a custom error handling, you will have to manually exclude the CSRF errors, if you are using the default one then a custom one should be provided which should exclude the CSRF errors as well.

Either way, you will have to check for errors with a method similar to this
