Cannot seem to add a custom parser to the parsers conf of fluentd

[punkle]

The following error appears when starting fluentd. It continues to start up fine however it does not seem to continue to configure any custom parsers that come after it.

[2023/06/21 15:18:14] [error] [parser:container_firstline] Invalid regex pattern (?<log>(?<="log":")\S(?!\.).*?)(?<!\)".*(?<stream>(?<="stream":").*?)".*(?<time>\d{4}-\d{1,2}-\d{1,2}T\d{2}:\d{2}:\d{2}\.\w*).*(?=})

It seems to be configured here https://github.com/aws-samples/amazon-cloudwatch-container-insights/blob/main/k8s-deployment-manifest-templates/deployment-mode/daemonset/container-insights-monitoring/fluent-bit/fluent-bit.yaml#L229

Same issue, I used fluent-bit.yaml mentioned here.
