The lambda Function class should validate the functionName. Currently the only restriction is that the name is less than equal to 64 characters: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-function.html#cfn-lambda-function-functionname

Use Case

Catching bugs during build time instead of when deploying.

Proposed Solution

if (functionName.length > 64) { throw Error }

Other

This is the error that I got recently:

1 validation error detected: Value 'veryLongFunctionName' at 'functionName' failed to satisfy constraint: Member must have length less than or equal to 64 (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: 5d3d811c-ff88-43db-b9e0-468197776ee0; Proxy: null)

• 👋 I may be able to implement this feature request
• ⚠️ This feature might incur a breaking change (technically we will limit function names, but those would be rejected by CFN anyways)

This is a 🚀 Feature Request
