From my perspective LGTM!

We could get feedback from folks that have been interested in this before shipping though.
And validate that question whether it's OK to have 1 package with ktx + the coroutines, or if it's going to be a problem for too many ppl

@maciejwalkowiak I've created the docs issue as well getsentry/sentry-docs#3628

[marandaneto]

I am trying to add support for sentry coroutine in the Spring Boot project given
Here

i am using implementation "io.sentry:sentry-kotlin-extensions:5.0.0"

but its throwing error

Execution failed for task ':controller:compileKotlin'.
> Could not resolve all files for configuration ':controller:compileClasspath'.
   > Could not find io.sentry:sentry-kotlin-extensions:5.0.0.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/io/sentry/sentry-kotlin-extensions/5.0.0/sentry-kotlin-extensions-5.0.0.pom
       - https://jcenter.bintray.com/io/sentry/sentry-kotlin-extensions/5.0.0/sentry-kotlin-extensions-5.0.0.pom
     Required by:
         project :controller

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.
```gradle.org/current/userguide/declaring_repositories.html

@iamkdblue

Support for Kotlin Coroutines is available as a Beta. Features available in Beta are still in-progress and may have bugs. We recognize the irony.

please use this version for now https://github.com/getsentry/sentry-java/releases/tag/5.0.0-beta.7, 5.0.0 isn't out yet

[iamkdblue]

@marandaneto

cant find SentryContext() and launch in spring boot
and i am using withContext(Dispatchers.IO) not launch, mostly launch(fire and forget) uses in android!

[marandaneto]

@iamkdblue please raise a new issue with your setup and what you're trying to do, it'd be easier to track it down and fix it if there are issues, thanks

[markallanson]

Tested this out in 5.0.1 but it doesn't seem to work. Using this with the grpc-kotlin support and providing a SentryContext to the CoroutineScope it creates, but when I am inside coroutines the Hub seems to resolve to the NoOpHub hence sentry errors are not reported anywhere.

Using sentry-spring-boot-starter to initialize Sentry, and outside the coroutines the Hub is resolved correctly.

[marandaneto]

@markallanson please raise a new issue with more detailed context, happy to look into it, thanks

[markallanson]

I got to the bottom of this, the sentry-spring-boot-starter wasn't initialising sentry before the SentryContext was created causing it to use the NoOpHub.

[marandaneto]

@markallanson so was it a bug in your end or what, does it mean you're creating the SentryContext before even initing Sentry?

[markallanson]

@marandaneto I need to try and get the sentry-spring-boot-starter to initialize sentry before my services try and use the context.
