panic: reflect: call of reflect.Value.Index on int64 Value

[dahu33]

I get the following panic message on one of our EKS clusters (all the clusters have the same fluent-bit config but only this one is getting a panic). It uses the "compatible" config described in AWS doc which currently uses the amazon/aws-for-fluent-bit:2.10.0 docker image.

panic: reflect: call of reflect.Value.Index on int64 Value

Potentially relates to fluent/fluent-bit-go#34 and fluent/fluent-bit-go#29 which seem to have been fixed over 8 months ago but the fix never made it to this repo.
