Pushgateway call registry async metrics methods

[zD98]

prom-client/lib/pushgateway.js

Line 78 in 25f9c40

req.write(this.registry.metrics());

metrics is an async method.

So should calling metrics with async/await ?

const metrics = await this.registry.metrics();
req.write(metrics);

Yes, I think you're right. I missed two high-level functions evidently :(. PR welcome, otherwise I'll fix it in the next few days. Thanks for finding that.

Hey guys @zD98 @zbjornson. I have just met the same bug. Do you have any plans to merge PR and release a new version?

This issue still occurs at version 13.Please publish a new sub-version to resolve it, thanks.

[zbjornson]

This was fixed in #419 (thanks @adorin). Until the new version is published, you can install from github using yarn add siimon/prom-client#83f7867 or npm i siimon/prom-client#83f7867.

v13.1.0 is now published with this fix!
