Serverless-split-stack plugin with provisionalConcrrency causing deployment error

Serverless Framework
1

Hi Guys, I have come across a condition where my project resource ran out of the 500 cloud stack limit of AWS, and because of that,
I was forced to use the serverless-split-stack plugin. It was deploying as expected without adding the provisionalConcurrency parameter to the function.
Upon adding this config deployment starts failing, Has anyone faced a similar situation ever? It would be great if someone could help me to resolve this issue.

getting error:

Stack dm-scratch-v2-test failed to deploy (1359s)
Environment: darwin, node 14.15.4, framework 3.34.0 (local) 3.34.0v (global), plugin 6.2.3, SDK 4.3.2
Credentials: Local, environment variables

The CloudFormation template is invalid: Template format error: Unresolved resource dependencies [AuthorizerFuncLambdaFunctionArnParameter] in the Resources block of the template
