fatal error: unexpected signal during runtime execution, fresh install 🤷‍♂️

[PierreBrisorgueil]

Describe the bug
On fresh ferret install, I got fatal error: unexpected signal during runtime execution when I return JSON.
Probably linked to: MontFerret/worker#27

To Reproduce
Steps to reproduce the behavior:

• go version go1.19 darwin/amd64

• go install github.com/MontFerret/cli/ferret@latest3.

• ferret exec --browser-open test.yml

RETURN 0

• ferret exec --browser-open test.yml

RETURN {'test': 0}

Expected behavior
No error

Desktop (please complete the following information):
Mac intel, ferret browser, latest

Additional context
strangely it works fine with binaries already made
https://github.com/MontFerret/cli/releases/download/v1.8.0/cli_darwin_x86_64.tar.gz

[ziflex]

Hmmm.
For some reason, jettison is causing the panic.

I will look into it.
Could you provide an example of a JSON value you are returning?

[PierreBrisorgueil]

Hey 👋,

Yes, it's just like in my previous post: RETURN {'test': 0} in the .fql is sufficient to reproduce the bug

[ziflex]

Hey, can you try this with the latest version?

[PierreBrisorgueil]

I will try asap, it was fixed on my worker with

replace github.com/wI2L/jettison v0.7.3 => github.com/wI2L/jettison v0.7.4
