Total timeout of API google.pubsub.v1.Publisher exceeded 60000 milliseconds before any response was received.

Hi all,

We're encountering below error:

Total timeout of API google.pubsub.v1.Publisher exceeded 60000 milliseconds before any response was received.

Initially, the service successfully publishes messages to a topic without encountering any errors. However, after the application has been running for a while, typically around 1-2 hours, errors begin to manifest. It appears that the pub/sub client retains all the messages in memory after the error occurs, leading to a gradual increase in container memory usage.

Environment details

• OS: nodejs20-debian12:latest
• Node.js version: 20
• npm version: 8.19.2
• @google-cloud/pubsub version: 4.3.3

Steps to reproduce

Publisher snippet:

async publishEvent(event: Event): Promise<void> {
    try {
      const messageId = await this.topic.publishMessage({
        data: Buffer.from(JSON.stringify(event)),
        attributes: {
          eventType: event.eventType,
          eventVersion: event.eventVersion,
        },
      });
    } catch (error) {
      logger.error(
        `Received error while publishing: ${(error as Error).message}`
      );
    }
  }

Subscirber snippet:

export async function setupPubSubSubscription(
  channel: string,
  callback: (message: string) => void
) {
  const subscription =  pubsub.subscription(channel);

  subscription.on("message", (message) => {
    try {
      callback(message.data.toString());
       message.ack();
    } catch (err) {
      const ackError = err as AckError;
      logger.info({
        error: `Ack for message ${message.id} failed with error: ${ackError.errorCode}`,
      });
    }
  });
  subscription.on("error", (error: Error) => {
    logger.error({
      type: "Pub-Sub Error",
      message: error.message,
      name: error.name,
      stack: error.stack,
    });
  });
  return subscription;
}

Hello everyone,

For those who will follow this issue,

We also use @google-cloud/secret-manager in our services, the version we had before any update:"^4.1.1".

Updating @google-cloud/secret-manager to the latest version available as of today, "^5.3.0", successfully resolved the problem.

This upgrade automatically updated the grpc.js version, which I believe to be the root cause and solution to this issue. Alternatively, it might involve adjustments to other internal dependencies utilized by secret-manager and nodejs-pubsub under the hood.
