If I use any of the functions of ngxtension I get the following output when doing SSG:

I'm trying to figure out what might be causing this. However I could only pinpoint that it was using anything of ngextension.
I don't have time right now to make an example.

Will try to make it tomorrow, but i'm making this issue to already keep track of it

We will need more information on this one.

Hi, @eneajaho,

I've found that it was an edge case using:

  • gql of apollo-angular
  • in a apollo query
  • in a derivedAsync

Removing the gql of the query and using it as unkown/any/TypedDocumentNode, would fix this error, still strange how this this would matter.

I don't know if this error is ngexension related or apollo related

I've created a template here: https://github.com/cskiwi/angular-nestjs-full-starter
if you would go to file: libs\frontend\pages\home\src\components\home\page-home.component.ts

There change

exampleFetch = derivedAsync(() =>
    this.apollo.query({
      query: `
        query Profile {
          me {
            id
            name
          }
        }
      ` as unknown as TypedDocumentNode,
    }),
  );

to

 exampleFetch = derivedAsync(() =>
    this.apollo.query({
      query: gql` // <-- use the gql import here
        query Profile {
          me {
            id
            name
          }
        }
      ` ,
    }),
  );

the error will show up

After some further investigation I was able to narrowed the issue down to my Apollo not being configured correctly for SSR/SSG.

Sorry to bother you with this issue. It wasn't easy to spot that it came from there :(
