Serverless middleware Error: Cannot find module 'notifications-dev-findLead' - amazon-web-services

Question

After a lot of tries I'm surrendering and asking this
this is my serverless.yml
console: true
service: notifications
frameworkVersion: '3'
useDotenv: true
plugins:
- serverless-offline
- serverless-dotenv-plugin
- serverless-plugin-typescript
- serverless-middleware
custom:
middleware:
folderName: middleware # defaults to '.middleware'
cleanFolder: false # defaults to 'true'
provider:
name: aws
runtime: nodejs14.x
versionFunctions: false
region: ${opt:region, 'sa-east-1'}
functions:
findAllLeads:
handler: src/server.findAllLeads
events:
- http:
path: leads
method: get
cors: true # <-- CORS!
findLead:
handler: src/server.findLead
middleware:
pre:
- middleware/middleware.myF
events:
- http:
path: leads/{id}
method: get
cors:
origin: "*"
createLead:
handler: src/server.createLead
middleware:
pre:
- middleware/middleware.myF
events:
- http:
path: leads
method: post
cors: true # <-- CORS!
and my project strcucture is something like
middleware/
middleware.ts
src/
servers.ts // with handlers
and my middleware.ts is
// export const middleware = (event: any) => {
// console.log(event.body);
// };
export const myF = (event) => {
// will do some logic if I make it work
console.log(event.body);
};
and ALL im getting is
{"message": "Internal server error"}
as a response and in the logs
Does anyone know how to fix this?
