I converted a Postman collection into a script for load testing tool k6 with postman-to-k6. Running the k6 test fails with this error message:
ERRO[0016] TypeError: Cannot read property 'set' of undefined or null
Run at executePrerequest (file:///home/dm/temp/39/k6/libs/shim/core.js:1187:203(89))

What do I have to change for the load test to work?
