Error "datadog:api key not configured" even though apiKeySecretArn is set

[philipwigg]

Expected Behavior

If I have apiKeySecretArn configured and the plugin is able to read the DD API key, I do not get an error in the logs complaining that

datadog:api key not configured, see https://dtdg.co/sls-node-metrics

Actual Behavior

I do receive an error that

datadog:api key not configured, see https://dtdg.co/sls-node-metrics

even though I don't need it to be configured because I'm using apiKeySecretArn as an alternative.

Specifications

• Serverless Framework version: 3.10.-
• Datadog Serverless Plugin version: 4.1.2
• Lambda function runtime (Python 3.7, Node 10, etc.): Node 14

Hi @philipwigg - thanks for reaching out!
This message comes from dd-lambda-js

We did just release a fix for this, but looking at your reported plugin version - that fix should be in your deployed runtime. (landed in 4.1.1).

Would you mind confirming for me that the version of the Datadog NodeJS Lambda Layer is 74 or greater?

Thanks!

I'm not sure how to check the Lambda layer version, how do I do that?

I wonder if maybe this.isAgentRunning is still undefined at the point that the getAPIKey method is called? getAPIKey is called by the constructor whereas this.isAgentRunning seems to be set only when onStartInvocation is called? I am not much of a developer so sorry if this is totally wrong!

Hi @philipwigg! The easiest way is to log into the AWS console, go to the Lambda function, and then inspect the Layers section. A screenshot would be sufficient.

Thanks!

Sure, here you go

Okay thanks - I'll look into this and get back to you!

Hi @philipwigg - there are a few things occurring here. It appears that apiKeySecretArn is not yet supported by datadog-lambda-js, which is why you're seeing the error.

This is only relevant to you if you're using sendDistributionMetricWithDate, which hits the API directly. Otherwise metrics are flushed to the extension (where apiKeySecretArn is supported).

We need to make several additional changes to support apiKeySecretArn. In the meantime, we should move this issue to https://github.com/DataDog/datadog-lambda-js
