Description

If setting logging level to TRACE (just minimum level is enough, not need to be shown level), some tests fail with error Cannot create PyString with non-byte value. This happens e.g. at Acceptance.Get.Get Requests.

This is probably some Jython issue, as there's no calls related to that in the library's code or in the stacktrace.

Run: mvn clean verify -Dtests="Get Requests" -DrobotLogLevel=TRACE

Error is content specific, as only that test (of get tests) seem to be failing because of it.

Research direction

Run mvn clean verify -Dtests="Get Requests" -DrobotLogLevel=TRACE and reproduce the failure in Acceptance.Get.Get Requests. Start with the stack-trace entry points robot/output/loggerhelper.py, robot/variables/assigner.py, and pprint.py, then compare TRACE behavior with lower levels. Done means the test completes without the Cannot create PyString with non-byte value error.
