Possible bug when using k6 version 0.40.0

[luanholiv]

Summary

Unable to parse and stringify .env files while executing the tests from dotenv.test.js file.

Steps to reproduce

1. Build a new k6 .exe

xk6 build v0.40.0 --with github.com/szkiba/xk6-dotenv

2. Run the tests in this repository

.\k6 run --verbose .\dotenv.test.js

Current behavior

Getting error messages:

"TypeError: could not convert function call parameter 0: could not convert FOO = bar SIZE = small to context.Context"

"TypeError: could not convert function call parameter 0: could not convert [object Object] to context.Context"

Expected behavior

Successful test execution.
