EvoMaster Version: 3.4.0

Hi @Tenpoless

thanks for reporting this issue. the read em.yaml config has problems. EvoMaster shouldn't crash, but rather give a better error message, as that stack-trace is quite confusing.
Did you modify em.yaml manually?
If so, could you paste it here?
If not, was it generated by a previous version of EvoMaster before 3.4.0?

thx

[Tenpoless]

Sorry for the late reply.

Yes, I modified the em.yaml file manually, but I still followed the template you provided.

Thanks

@Tenpoless thanks for providing this example

[arcuri82]

@Tenpoless is that example the one that led to that error message? I tried to reproduce it, and a get a different error:

which tells you the problem, you have an unknown field called email.
still, we should get a better error message not flooded with stacktraces...

[Tenpoless]

Thank you, the previous problem has been resolved and black box testing is running. The OpenAPI I tested uses JWT tokens and I had trouble adjusting the evomaster. I am looking for a solution using ChatGPT and I have to install MVN and JDK, but an error occurs.

Thanks

[arcuri82]

look at https://github.com/WebFuzzing/EvoMaster/blob/master/docs/write_driver.md

you are importing the wrong dependency evomaster-client-java. you should rather import evomaster-client-java-controller

[arcuri82]

btw, for using black-box testing, there is no need of EM Java libraries to generate tests. those are only needed for white-box testing.
