Problem

Hello,

I'm trying to post logs/metrics from Lambda function to Vector Aggregator using DataDog lambda extension. This should be now supported see this

I get an error when i test this:

The error is:

024-01-16 15:26:14 UTC | DD_EXTENSION | DEBUG | The payload was not too big, returning the full payload
2024-01-16 15:26:14 UTC | DD_EXTENSION | DEBUG | The payload was not too big, returning the full payload

{
    "code": 400,
    "message": "Error parsing JSON: Error("invalid type: map, expected byte array", line: 1, column: 12)"
}

Configuration

I'm injecting the Vector URL to the Lambda function as environment variable as below:

DD_VECTOR_LOGS_ENABLED    true
DD_VECTOR_LOGS_URL    https://vector-agg.test.com/
DD_VECTOR_METRICS_ENABLED    true
DD_VECTOR_METRICS_URL    https://vector-agg.test.com/

The lambda code I'm testing with is forked from here.

In Vector Aggregator there's a DataDog agent source configured as below that sinks to stdout:

  sources:
    datadog_agent:
      address: 0.0.0.0:8282
      type: datadog_agent
      multiple_outputs: true

### Version

vector 0.32.1 (x86_64-apple-darwin 9965884 2023-08-21 14:52:38.330227446)

I changed this to a feature since the datadog_agent source wasn't designed to receive data from the Datadog Lambda Extension. Thanks for opening!

[bharathiram]

Any update on this feature?

[bharathiram]

Is there a workaround solution for this error we can rely upon till we get the datadog_lambda_extension as a source?

[jszwedko]

As a workaround, though I haven't tested this, I think you could likely use the http source to receive the log events and the datadog_agent source to receive metric events. The http source just doesn't do the same parsing of incoming payloads.

Hey all, any news on this? Is it still unsupported?
