Unhelpful logs

[greg0ire]

We get the following kind of logs once in a while: Request missing required field: code=400, events=[{"event_type":"[Experiment] Assignment","time":1764943694841,"insert_id":" 2292430750 20427","library":"amplitude-go/1.0.1","event_properties":{"08c4e909-cc12-443e-b794-a8

We suspect what's missing is the device ID (other logs tell us so.

It seems there is a logging issue though. It looks like we should receive Request missing field: <name of the field> here.

I believe it comes from this line

analytics-go/amplitude/plugins/destination/internal/amplitude_response_processor.go

Line 71 in c2792ab

p.Options.Logger.Errorf("%s: code=%d, events=%s", result.Message, result.Code, eventsJSON)

Expected Behavior

we should receive Request missing field: <name of the field>

Current Behavior

Request missing field: <nothingness> code=400…

Possible Solution

Steps to Reproduce

Environment

• SDK Version: analytics-go v1.0.1
• Go Version: 1.25
• OS Info: linux

Hi @greg0ire, we have different error responses depending on whether the missing field is on the request object or in one of its contained events. While the SDKs have some additional logging for missing fields at the request level, the event level returns the error message from the server, which unfortunately is the same for both cases. I've reached out to our backend team to improve this.
