Which version of the plugin serverless-middleware supports function level middleware and whats the syntax

[javedinfinite]

I am trying to implement middleware at function level by following this doc.
But the middleware function I have written in a separate file and referenced in the serverless.yml is not even getting deployed (I checked by downloading the lambda function) i.e. middleware at function level not even getting registered.
Any idea where I am missing something?
Note: the middleware at package level is working perfectly but I have a requirement to implement it at function level.

Node version used: 14
"serverless": "^2.66.0",
"serverless-domain-manager": "^5.1.0",
"serverless-dotenv-plugin": "^3.10.0",
"serverless-middleware": "^0.0.15",
"serverless-offline": "^8.5.0",
"serverless-openapi-documentation-v2": "^0.4.6",
"serverless-plugin-typescript": "2.1.0",
"serverless-prune-plugin": "^1.6.1",

Below is the sample code of the serveless file:

provider:
  name: aws
  runtime: nodejs14.x

functions:
  my-function:
  middleware:
    pre:
      - src/authMiddleware.authenticate
    post:
      - catch: src/catchHandler.catchErrors
  handler: src/handler.users	
  timeout: 30
  events:
    -service: your-service-name

plugins:
  - serverless-dotenv-plugin
  - serverless-offline
  - serverless-middleware
  - serverless-domain-manager
  - serverless-plugin-typescript
  - serverless-openapi-documentation-v2
  - serverless-prune-plugin

custom:
  middleware:
    pre:
      - src/initialMiddleware.init
    pos:
      - catch: src/catchHandler.catchErrors

Hi,

You are usign version 0.15 of the middleware package whereas the latest version is 3.1.0.
You should upgrade as there were breaking changes on the major version releases.
