Invalid response from metadata service: incorrect Metadata-Flavor header

After reviewing as much as I could online to see how I could solve the issue, I wasn’t able to come to a solution, this is an issue apparently with how the JSON file holding the credentials to GCloud.

“Invalid response from metadata service: incorrect Metadata-Flavor header”

That is normally the error that keeps throwing the client when I invoke the alert function of the client.

Environment details

• OS: macOS Mojave
• Node.js version: v10.15.2
• npm version: 6.10.0
• @google-cloud/logging version: 5.2.1

Steps to reproduce

1. Generate a quick Angular project using the CLI
2. Make sure to have a JSON file with service account credentials properly downloaded.
3. Generate a quick service that looks somehow like it follows, inject it, and call the function that performs the logging.

`import { Logging } from ‘@google-cloud/logging’; @Injectable() export class GCloudLogService { constructor( private readonly logging: Logging, ) {}

    async saveLog(logPayload: IServerExceptionLog) {
try {
	const metadata = {
		resource: { type: 'global' },
	  };
	const entry = this.logging.entry(metadata, logPayload);
	const log = this.logging.log(logName);
	await log.alert(entry);
	return;
} catch (err) {
	console.log(`ERR ${err.message}`);
}

} }`

No matter how many versions of the code I try I keep getting the error:

“Invalid response from metadata service: incorrect Metadata-Flavor header.”

I tried setting the project manually,

await this.logging.setProjectId({ projectId, });

but still nothing.

I did make sure that the environment variable GOOGLE_APPLICATION_CREDENTIALS was set up and it is.

Please help, I have expended too many hours trying to figure it out but still nothing.
