Bundling to UMD error could not resolve 'my-service' from dist\fesm5\my-api-name.js

Since this week-end the client code generation for angular 8.2.7 typescript from a swagger open-api 3 spec file stopped working:

------------------------------------------------------------------------------

Compiling TypeScript sources through ngc
Bundling to FESM2015
WARNING: 'HttpResponse', 'HttpEvent' and 'HttpParameterCodec' are imported from external module '@angular/common/http' but never used

Bundling to UMD
ERROR: Could not resolve './my.service' from dist\fesm5\my-generated-api-name.js

I tried to revert to previous version of "@openapitools/openapi-generator-cli": "0.0.19-4.1.2" to version "0.0.19-4.1.1"

I also tried a dummy open-api 3 spec test file at https://petstore.swagger.io/ and I got the same error

The debug log says nothing I'm clueless

Here is the npm command I run:

"generate-front": "openapi-generator generate -i http://localhost:22953/swagger/v1/swagger.json -g typescript-angular -o ./code-front -c options-front.json"

Here is the option file:

{
    "npmName": "@my-company/my-api",
    "npmVersion": "0.18.0",
    "ngVersion": "8.2.7",
    "serviceSuffix": "Repository",
    "modelSuffix": "Model"
}

It should build without error

Solution

  • The problem was with ng-packagr it installed the latest version who has a breaking change

    "ng-packagr": "^5.4.0"

    I removed the hat and everything went fine:

    "ng-packagr": "5.4.0"

    Voilà!
