Cannot upload source maps

Elastic Observability APM
1

I am trying to enable client side error logging using RUM.

I have used these pages to guide me
https://www.elastic.co/guide/en/apm/agent/js-base/current/sourcemap.html
https://www.elastic.co/guide/en/apm/server/current/sourcemaps.html

I've tried it both in Postman and Javascript and I always get the following response:

{
"error": "Content-Type header [multipart/form-data; boundary=--------------------------037463214125015102208974] is not supported",
"status": 406
}

The boundary number changes on each request.
What is going on here?

Elasticsearch version is 6.5.4

Hello!

That sounds like the multipart/form-data is not correct; I don't know how Postman sends the request behind the scenes, but with curl you can do it like so:

curl -v -X POST http://127.0.0.1:8200/assets/v1/sourcemaps -F service_name="test-service" -F service_version="1.0" -F bundle_filepath="http://localhost/static/js/bundle.js" -F sourcemap=@bundle.js.map

Do you get the same error if you try it like that?

Yes it is the same; Here is the output

Jordans-MacBook-Pro:example jordan$ ls
bundle.js.map
Jordans-MacBook-Pro:example jordan$ curl -v -X POST https://[redacted].eu-west-1.aws.found.io:9243/assets/v1/sourcemaps -F service_name="test-service" -F service_version="1.0" -F bundle_filepath="http://localhost/static/js/bundle.js" -F sourcemap=@bundle.js.map
Note: Unnecessary use of -X or --request, POST is already inferred.

Hi,

I unfortunately can't reproduce it. Just to double check, you are also using Apm Server 6.5 and not setting the content type header at any moment, right? And you are POSTing that to the APM Server directly and not to any proxy.

Could be the case that the sourcemap is not correctly generated? If you wget this one https://github.com/elastic/apm-server/blob/master/testdata/sourcemap/bundle.js.map and POST it in the same way, does it work?

Thanks, your last comment about APM Server made me think about what I did - problem is solved.
I was sending the request to elastic search instead of the apm :confused:
The same request to elastic search will attempt to create an index

Glad to hear you got it, have a good day.
