GCP pub/sub client is failing above version 4.0.0 with auth error

Question

This happens when I try to create a topic

   TypeError: this.auth.getUniverseDomain is not a function
        at GrpcClient.createStub (/Users/<...>/node_modules/google-gax/src/grpc.ts:418:48)
        at processTicksAndRejections (node:internal/process/task_queues:95:5)

Sample Code:

pubSubClient = new PubSub({
      "projectId": "project_name"
    });

initTopic = async () => {
    // Creates a new topic if it does not exist
    const [topics] = await this.pubSubClient.getTopics()
    RootLogger.info("topic names: " + topics.join(","))
    const topicExists = topics.some(topic => topic.name.endsWith(this.topicName));

    if (topicExists) {
      RootLogger.info(`Topic ${this.topicName} already exists.`);
    } else {
      await this.pubSubClient.createTopic(this.topicName);
      RootLogger.info(`Topic ${this.topicName} created.`);
    }
  }

Same problem, started about a week ago without any meaningful code changes. – Mouton

I have fixed it by downgrading to 3.7 – Laconism

The issue is opened on github in the google auth package. link 1 link 2 link 3 – Civil

The third one was raised by me :P – Laconism

Answer 1

As @vizsatiz mentioned in the comment:

The error TypeError: this.auth.getUniverseDomain is not a function was solved by downgrading it to 3.7. The problem occurred when using the pub/sub client above version 4.0.0. As a workaround, anyone facing the same issue with the version above 4.0.0 can consider downgrading the version as a first step.
