[gauravbrills]

Hi I might be missing something here but I get this error when I do a mvn spring-boot:run or run the test case customControllerReturnsDefaultMediaType

any idea ,or is it some jar issue ?

[myndworks]

Yes, I am getting the same error. I am on Mac.

• Application boots ok
• when I tried http://localhost:8080/ got this error
• and I tried to run the unit tests, some tests fail with the same error.
• something to do with jackson??
• Thank you for your help. I would dearly like to see this working. Cheers..

[igler]

It seems to be a problem with <spring-hateoas.version>0.18.0.BUILD-SNAPSHOT</spring-hateoas.version> at the moment. If you switch to <spring-hateoas.version>0.17.0.RELEASE</spring-hateoas.version> in your pom.xml then things should work again.

[myndworks]

Yes, that fixes the issue. All tests are ok. Thanks heaps.

[claboran]

Hi,

still have a problem with the example. Even switching back to version 0.17.0.RELEASE. This happens when starting spring boot app. Thanks for help.

After switching to

<spring-hateoas.version>0.19.0.BUILD-SNAPSHOT</spring-hateoas.version>

everything is fine. Event the tests are working :-)
