UnhandledPromiseRejectionWarning: Error: Unrecognized element: kg.apc.jmeter.threads.UltimateThreadGroup

I get the following error when I try to convert a jmx file to k6.

Thanks for the report @Sand038. That UltimateThreadGroup seems to be an unsupported element. (Maybe a custom element from a plugin?)

You might be able to get it running if you could rebuild without that element.

Closing due to lack of response.
