aws-cdk/lambda-layer-kubectl-v27: Found CDK v1 deps in your project, even though your "cdkVersion" is 2.x.

[lmouhib]

Describe the bug

When using kubectl layers for newer version, CDK complain that the layer still uses CDK V1.

Expected Behavior

CDk should not complain and the lambda layer library should use CDK v2

Current Behavior

CDk should not complain and the lambda layer library seems to use CDK v1.

According to this the v27 module should depends on cdkVersion 2.28.0

Are you running projen in your current project with your own .projenrc.ts? I am not sure if this warning is coming from the layer. What is the cdkVersion in your .projenrc.ts ?

[lmouhib]

@pahud here is the .projenrc.ts link.

We also get the warning if we run a cdk deploy, without using any projen helpers.

We have this same issue within our internal CDK library as well whenever we are compiling the project, an older version of kubectl layer, but we also did run into the same issue of it complaining about v27, and v28 if those are added as well.
