Solved! I had a similar problem with another library and here I explain the problem in detail. https://github.com/MrGraversen/rust-rcon/pull/2

The error in short, is that Gson from JDK 12 fails, even if you compile in a previous java. The solution is to go to the latest version of Gson

Edit: Reviewing I have seen that you have the latest version of playwright. Probably then, that you are trying to use an older version and not the latest one.

Edit 2: Ok, in the latest version you don’t define the gson version, project can try to use another version. In the new one, you do define it to the latest version.

Thanks for the thorough investigation!

In the current version of playwright it does not specify the required version of gson.

The version is specified the dependency management section of this pom.xml which is specified as parent project for playwright. As far as I understand this should enforce the version for all submodules but it looks like it does not happen in your case.

I’m closing this for now, but please feel free to reopen if you believe we can fix it on playwright end.
