I am now having a problem which says:

same issue.

@lessthanjake328 are you sure you got past the original error, the error in the OP is raised when trying to run the RNTester app in this repo. Your subsequent changes sound like custom code.

Here is a screenshot of the RNTester error

Hey there, it looks like there has been no activity on this issue recently. Has the issue been fixed, or does it still require the community's attention? This issue may be closed if no further activity occurs. You may also label this issue as "For Discussion" or "Good first issue" and I will leave it open. Thank you for your contributions.

[DavidSBowen]

@morenoh149 no there was no custom coded added to the RNTester. I wouldn't have customized anything in the Tester. I only wanted to use the tester to view various available components in RN. The issue continued to occur as long as I tried using RNTester. It has been a while, so there is a possibility it is fixed now, but I have not tried using RNTester since my last post.

BTW I am the OP :)

[morenoh149]

yeah it's worth trying the latest RN, fixes are constantly going out and issues become inaccurate. For example I get this error in the packager

internal/modules/cjs/loader.js:596
    throw err;
    ^

which results in the red screen I shared above. This is the RNTester project currently on master using cocoa pods.

[DavidSBowen]

I'll go ahead and close this since it is an old issue and is just taking up space.
