Errors on previously running Javascript/Mocha iOS Automation

A few months ago I had some Appium automation running successfully in Javascript using Mocha. I’ve moved over to a new laptop and app and replicated the same structure, but I’m receiving the below errors. Any help would be greatly appreciated!:

Can you try running Appium Doctor?

This is my appium-doctor outcome:

You should fix the problems.

I’ve fixed some of them, but I don’t see how any of them are contributing to my issue.

opencv4nodejs and ffmpeg are for images and screen recording (irrelevant), bundletool.jar is for Android (irrelevant) and idevicelocation is used to set geolocation manually (irrelevant)

Ok, full disclosure: I am not a javascript programmer. In my experience this board does best with Java questions, with most other languages having spotty knowledge at best.

I did some research but I can’t find what could be causing your error. If you have the old laptop still I would suggest the following:

  1. Run Appium Doctor there and compare the two. Maybe that would show you something that can be fixed.
  2. Try some kind of diff tool (Beyond Compare is good for this) on the two machines (just in the automation folder) to see what kind of differences you might find.

Finally, I found a good tutorial on the error you are seeing. Don’t know if it will help:

Good Luck.

Thanks, I’d done some digging and discovered that it’s a result of a lot of changes when Webdriver released v5 which broke a lot of existing functionality. So I’m going to have to go back to the drawing board and try and rewrite it.

I want to know how to solve the problem of idevicelocation cannot be found, I also met this problem, please advise, thank you
