SAP CAP: Error Starting Service After Deployment MODULE NOT FOUND requireStack

[Cristian]

Hi experts,

We have a CAP services that is using a set of custom .js files.

We are getting the error below after deployment when trying to start the service.

"error":{"code":"MODULE_NOT_FOUND","requireStack":["/home/vcap/app/srv/utils/xmlUtils.js","/home/vcap/app/srv/utils/validationHeader.js","/home/vcap/app/srv/controller/validationHeader.js","/home/vcap/app/srv/edi-code-to-order-srv.js"]}

Odd thing is that if we execute the service from BAS everything works fine but not able to deploy.

We have an event handler implemented named edi-code-to-order-srv.js for our edi-code-to-order-srv.cds. Here we have an import of a custom .js.

const cds = require('@sap/cds')
const { executeHttpRequest } = require('@sap-cloud-sdk/http-client')
const { validationHeaderControl } = require('./controller/validationHeader');

This custom .js has other requires of other custom .js and it is place within the srv folder.
