k6 v0.34.1 is a patch release with a few minor bugfixes:

• There was a minor bug in the new k6/execution API added to k6 v0.34.0 - some of its properties weren't usable with the externally-controlled executor (#2132).
• goja, the JavaScript runtime that k6 uses, was updated to its latest version (#2135), which fixed a couple of bugs:
  • A newly introduced JS bug from k6 v0.34.0, where rest parameters were undefined when the functions also had an internal lambda (#2131). Thanks for reporting, @efdknittlfrank!
  • An old JS bug, first introduced in k6 v0.28.0, which caused Response.json() to not have a length property when the response was a JSON array, i.e.response.json().hasOwnProperty('length') was returning false (#2133). Thanks for reporting, @julien-sugg!
