Is it possible to ignore an exception in AWS lambda to be added to the "Errors" metric?

My issue is as follows - I have a lambda function attached to API gateway, where i map some error codes using integration response.

The thing is, i can only map errors if the lambda function fails (throws an exception).

This makes the "Errors" metric kick in - https://docs.aws.amazon.com/lambda/latest/dg/monitoring-metrics.html#monitoring-metrics-invocation

We monitor this metric, and we get now email alerts also there's an exception for invalid input, or something else that is fixable by the user (and should not trigger an error metric).

Is there any way to ignore certain errors from being written as an error metric?

Thanks.

The way I see it, if you know exactly which kinds of errors you want to ignore, you should use try ... except blocks (or equivalent, depending on which language you use) in your lambda targeting those specific errors.

This way you can initiate graceful exit without failing lambda execution.
