Re: [akka-user] Uncaught error from thread - ContentType$WithMissingCharset

[Konrad “ktoso” Malawski]

The exception is pretty clear about something being wrong with dependencies:

> java.lang.NoClassDefFoundError: akka/http/scaladsl/model/ContentType$WithMissingCharset

How do you configure this project? 

What’s your dependencies / build file / build system?

Thanks for quick reply, Konrad.

Actually, I'm using - these json parsing dependencies in Gradle.

compile group: 'org.json4s', name: 'json4s-native_2.12', version: '3.2.11'
compile group: 'org.json4s', name: 'json4s-jackson_2.12', version: '3.5.0.RC1'
compile group: 'de.heikoseeberger', name: 'akka-http-json4s_2.12', version: '1.17.0'

And, I modified the function actually, where I'm using jackson.parseJson(info) like this -

Unmarshal(res.entity).to[String] map {
            info =>

              jackson.parseJson(info).children.length

Am I doing something wrong here?  or something wrong in Parsing using json4s?

Actually depend on akka-http 10.0.10 and akka 2.5.6 ;-)

Ok. I'm currently using 

akkaHttp: "10.0.7", akka: "2.5.2". Is there an issue? Or What packages I should be using?

[bord...@gmail.com]

Even I'm surprised, it is working fine for many requests if I fire it from Firefox and crashes with the above error after like 5-6 requests made.

But , in Chrome it crashes with the same error after 1st request itself (showing me the output).

Regards,

Aditya Borde

[Konrad “ktoso” Malawski]

Weird indeed;

With regards to versions, please always use the latest - esp when reporting issues like this.

Please try 10.0.10 and 2.5.6 as I suggested above.

Can you post a reproducer (repository) where we could reproduce this?

Hi Konrad,

I think, the above VERSIONS resolved my issue. Thank you very much for the response. I tested my code and it is working now.

(I'm working for a company so, hard to share the code.)

Happy hakking, cheers :)
