node.js - AXIOS_INSTANCE_TOKEN error in Nestjs startup

Question

My nestjs app starts to blow up pointing to AXIOS_INSTANCE_TOKEN error and request for the module containing AXIOS_INSTANCE_TOKEN to be imported... the thing is the only module using Axios is HttpModule and it was imported from the start. this is what I have:

the error:

[0] Potential solutions:
[0] - If AXIOS_INSTANCE_TOKEN is a provider, is it part of the current AppModule?
[0] - If AXIOS_INSTANCE_TOKEN is exported from a separate @Module, is that module imported within AppModule?
[0]   @Module({
[0]     imports: [ /* the Module containing AXIOS_INSTANCE_TOKEN */ ]
[0]   })

THIS IS THE APP MODULE:

......   
@Module({
  imports: [
    RavenModule,
    ConfigModule.forRoot({
     isGlobal: true,
     load: [configuration],
       }),
    HttpModule.register({
        timeout: 5000,
        maxRedirects: 5,
      }),   
    AuthModule,
    UserModule,
   .......

I noticed that the three references to HttpModule initialized ok. Also, I have a check and the two other modules with HttpModules have correctly imported HttpModule in the Module and the injected the HttpService in the Service. I also noticed that the build died while building ConfigModule...not sure what that means?.... I have also deleted node_modules and run npm I twice and upgrade my nestjs/common from 7.5.1 to 7.6.11 all to no avail.

I would really appreciate any insights on this! Thanks in advance.

Answer 1

Apparently I somehow included HttpService in the app module as a provider and exported it also. Removing both entries resolved the problem.
