[BUG] v2.transactionDroppedSpansDurationSum.Us: assertInteger: can not decode float as int

[gnulp]

APM Agent version

1.25.0

Environment

Windows Server 2019

.NET Core 7.0.13

ASP.NET CORE

Describe the bug

Following error occures randomly in log files:

{PayloadSenderV2} Failed sending event.
APM Server response: status code: "BadRequest", content:
decode error: data read error: v2.transactionRoot.Transaction: v2.transaction.DroppedSpanStats: []v2.transactionDroppedSpanStats: v2.transactionDroppedSpanStats.Duration: v2.transactionDroppedSpansDuration.Sum: v2.transactionDroppedSpansDurationSum.Us: assertInteger: can not decode float as int, error found in #10 byte of ...|{"us":1940.382199999|..., bigger context

To Reproduce

Steps to reproduce the behavior:

1. Use this config '...'
   ElasticApm:CentralConfig = false
   ElasticApm:LogLevel = "Error"
   ElasticApm:OpenTelemetryBridgeEnabled = false
   ElasticApm:CloudProvider = "none"
   ElasticApm:CaptureHeaders = false
   ElasticApm:CaptureBody = false
2. Then call '....'
   any page
3. Then do '....'
   random usage of page
4. See error
   exception in log

Hint:

as stated here:
https://www.elastic.co/guide/en/apm/guide/current/api-transaction.html
the field "Us" is defined as integer:
"us": {
"description": "Us represents the summation of the span duration.",
"type": [
"null",
"integer"
],
"minimum": 0
}

But in this file:
https://github.com/elastic/apm-agent-dotnet/blob/v1.25.0/src/Elastic.Apm/Model/DroppedSpanStats.cs
in line 72 we see type "double"
Might this be the problem?

I also have this issue and opened an issue #2200 which references a issue in the agent-nodejs package which got already fixed
