NGINX log format with escape parameter not matching

[im-redactd]

When I define the escape parameter in the nginx config the honeytail parser thinks its part of the expected value instead of skipping it as a param.

nginx conf snippet:
log_format customFormat escape=json '$remote_addr -

honeytail with debug snippet:
does not match given format '^scape=json '(?P<remote_addr>[^ ]*) -
