I'm trying to convert the file attached, but I'm getting the error below:

Hey,

Thank you for the report! Reproducing this error made me find two hard-spotted regex errors that have now been fixed. However, the reason that your conversion is failing is because you utilize __RANDOM, a Jmeter helper not supported by the converter.

The easiest way to get around this is by stripping your jmx of this call, and then substitute it with a call to randomIntBetween in the final output. randomIntBetween is directly require:able from https://jslib.k6.io/k6-utils/1.0.0/index.js

Thanks,
Simme

Thank you for getting back to me, I'll pass this to the performance team so they can make the required changes and let you know.
Thanks again for your help :)
