[BUG] (type-safe-api) PrepareSpec function name too long

[jstrunk]

Describe the bug

type-safe-api generates prepareSpecLambdaName using the stack prefix. When used with a branch name and stack name over a certain length, it causes a function name longer than 64 characters which is the limit from Lambda.

Expected Behavior

All generated function names will be less than 64 characters in length.

Current Behavior

cdk synth fails with Error: Function name can not be longer than 64 characters but has 66 characters.

The full error message before this exception appears to be a dump of a javascript source.

Reproduction Steps

Create a stack with a type-safe-api in a stack with a name over 34 characters long. Or use PDK Pipeline with feature branches enabled and have the combination of the branch name and the stack name over 34 characters long. e.g. feature-branch-Dev-MyLongStackName.

cdk synth will fail

Possible Solution

https://github.com/aws/aws-pdk/blob/4057d69b68e329d7434af4c3cd0ef7d17856c8b2/packages/type-safe-api/src/construct/type-safe-rest-api.ts#L128C11-L128C32 generates the ParseSpec name.

aws-pdk/packages/type-safe-api/src/construct/type-safe-rest-api.ts

Line 224 in 4057d69

const providerFunctionName = `${prepareSpecLambdaName}-Provider`;

uses it and appends "-Provider" for a second function.

Create a function to check the length and generate a shorter alternative.
