Detox failed to start testing in my react native project

[Milesyan]

I'm using react native 0.52.0 and detox 7.0.1. I got the error messages as below, and I cannot find a similar issue.

The build built by detox can be opened without crash when I directly open it in the simulator, just crashed when I run detox test

Hi,

Thanks for reporting.
I see you are also using TrustKit.
Could you please create a demo project with TrustKit and upload it for us?

Thanks

All, did you fixed this issue because i have the same issue in my project:

@paulvelzeboer Were you able to fix this? Same issue for me

[paulvelzeboer]

@BenBach nope still same issue... hopefully someone has a solution?

[LeoNatan]

@paulvelzeboer In #645, I asked for an example project reproducing the issue with TrustKit. Please provide that so I can take a look.

[DanielMSchmidt]

Hey @BenBach & @paulvelzeboer Could you create a demo project, so that we can reproduce and find the bug? It would be cool if it would be something like the smallest project possible that shows this error 👍 Thank you for helping us :)

[DanielMSchmidt]

Ah @LeoNatan two idiots one idea ✋ 🤣

[LeoNatan]

Please don’t reopen old issues. Once the demo project exists, open a new issue.

[LeoNatan]

@DanielMSchmidt Hehe. I asked for a demo project twice, but I was never provided with one.

[Milesyan]

I wanted to provide one but I don't know how as I'm not an iOS developer... I'll try to do it next week.

[LeoNatan]

I meant a React Native demo project. Please open a new issue with the project.

[paulvelzeboer]

Same here i know you need a project and will discus with our developers if they can create a demo project (project we are working on now i cannot share) and will send it to you, if there is an issue already open than i can add mine or if im the first one open a new issue

[LeoNatan]

Great, thanks
