iam_service.json not found

ERROR

I get the following error when I try to use the pubsub client. In my cloud function environment calling pubsub nodejs client.

Warning: iam_service.json not found in any of the include paths

Environment details

• OS: Cloud functions
• Node.js version: 12.20
• npm version: yarn 1.18
• @google-cloud/pubsub version: 2.10

Steps to reproduce

Trying to instantiate a pubsub client

/**
*  This service account has full access to pubsub on this project.
*  I logged all credentials as well and they are correct.
*/
const sa = functions.config().pubsub.key;

const pubsubClient = new PubSub({
    projectId: sa.project_id,
    credentials: sa, // this is the service account json file (also tried only as { client_email, private_key } same error
});

Call function where client is used:

export const publishToTopic = async (details: { topic: string; body: any }) => {
    try {
        const data = JSON.stringify(details.body);
        const dataBuffer = Buffer.from(data);

        await pubsubClient.topic(details.topic).publish(dataBuffer);

        return;
    } catch (error) {
        console.error(JSON.stringify(error));
    }
};

Get error Warning: iam_service.json not found in any of the include paths

Any help would be appreciated! Due to how cloud functions work I can't seem to use the option of passing a keyFilename path

Note I did try following this: #1000
but it still throws IAM error

@bytewiz That sounds annoying. Let me see if I can find someone who knows a bit more about Cloud Functions (@bcoe ?). If that doesn't turn anything up, I'll be able to look at this next week.

Thanks that would be great! Would really love to use it so that would be helpful 🙏

@feywind nothing after 2 weeks? 😞 would be nice to know something about this, as we plan to use pubsub quite a bit with cloud functions
