misdocumented breaking change in v3

[zwing99]

Is there an existing issue for this?

• I have searched the existing issues

Kong version ($ kong version)

3.0

Current Behavior

in 2.X if you defined target_path on the service it was ignored by the aws-lambda plugin and never prepended to the path set sent in the json payload to lambda

Expected Behavior

In 3.X if you define target_path on the service it is prepend and this is apparently expected. HOWEVER, this is a breaking change to those expecting the target_path to be ignored. Can the changelog be update to reflect that #9058 and #9129 are in fact breaking changes to the 3.0 release.

Steps To Reproduce

1. Set target_path on service
2. Use aws-lambda plugin in 2.x vs 3.x

Anything else?

Please update the docs.

@oowl , I think that you are those PR's author, could you take a look at this issue? thanks.

@oowl and @chronolaw any updates here? Others? My organization had to roll back our upgrade from 2 -> 3 because of this breaking change. We need to make changes to the config before we can upgrade. It is our fault for configuring kong incorrectly and depending on bad behavior. However, patching this bug is a breaking change and I am just hoping to help others to hopefully catch it when reviewing the changelog.

IMO, fixing a buggy behavior is not a breaking change. It's arguable whether we should consider fixing a bug used as a feature in a special case. @oowl votes for you and you need another vote to change the changelog.
