offest can't be higher than max integer value for viewing messages

[doug2525]

Get below error when trying to read messages "Failed to convert property value of type [java.lang.String] to required type [java.lang.Integer] for property offset; nested exception is java.lang.NumberFormatException: For input string: "5659373885" "

Hey @doug2525 , we have some changes coming soon (this week hopefully) that change the internal data type of the offset field inside the MessageInspectorForm class to long, which should solve this.

[doug2525]

@michael-pratt That is great!! thanks for the quick response.

[michael-pratt]

@doug2525 We just pushed the latest version of code out on master, give it a try and let us know if it resolves your issue.

[doug2525]

@michael-pratt that seems to have corrected the issue. Thanks. Is there a list of updates for this version somewhere?

[doug2525]

@michael-pratt I found a bit of an issue with this new version. Any topics that have names that end in .json when you click them to get the topic details it shows json for the topic details. Other topic names seem fine.

[doug2525]

Here is an example of what I'm seeing when I click on the topic name

[michael-pratt]

@doug2525 This is a spring artifact. By default it uses the URL to try and determine what content type to send back. With the .json extension on some of your topic URLs, Spring thinks you want JSON back, and we now have endpoints that provide that (previously there was only one mapping).

Can you try adding this snippet in the Kafdrop.java and let me know if it helps?

@Bean
public WebMvcConfigurerAdapter webConfig()
{
   return new WebMvcConfigurerAdapter()
   {
      @Override
      public void configureContentNegotiation(ContentNegotiationConfigurer configurer)
      {
         super.configureContentNegotiation(configurer);
         configurer.favorPathExtension(false);
      }
   };
}

@michael-pratt not much of a java developer so it could be me not doing something correctly but anywhere I add the snippet into the KafDrop.java maven can't resolve the objects.

[michael-pratt]

@doug2525 My guess is you were missing the import statements. You can try this branch if you want:

https://github.com/HomeAdvisor/Kafdrop/tree/json_topic_fix

I tested locally with a test topic that ended in .json and it appears to fix the problem. We'll try and work the permanent fix into an upcoming unit of work, but that branch should work in the meantime.

[doug2525]

@michael-pratt ya the import statements did the trick. The issue appears to be resolved with the snippet. Definitely let me know once you have the permanent fix in place and thanks.
