React Native (Expo) not working with TanStack Form

[RobertOstermann]

Describe the bug

Describe the bug

Not sure if this is a bug or just an issue with how I have everything setup. I get an error whenever trying to use TanStack Form with React Native (Expo).

Your minimal, reproducible example

N/A

Steps to reproduce

• Create a React Native (Expo) project
• Setup TanStack Form. I used createFormHook to reduce boilerplate.
• Attempt to run the project using React Native on an IOS simulator
• Note the error: "Uncaugh Error: (0, _classPrivateFieldLooseBase2(...)_eventTarget]().addEventListener is not a function (it is undefined)

Expected behavior

TanStack Form should work for React Native out of the box without any additional configuration.

How often does this bug happen?

Every time

Same error happens to me after upgrading to SDK 54. Any fix?
(Edit: Upgrading from 1.12.1 to 1.20.0 fixed the issue for me.)

[RobertOstermann]

Interesting, looks like v1.20.0 is working, but v1.21.1 is not for me. I can use v1.20.0 in the meantime. Does v1.21.1 also not work for you?

+1 on 1.21.1 + expo 54

Same here (on 1.21.1) with bare react native 0.81.4, but i get TypeError: crypto.randomUUID is not a function (it is undefined), It was working on 1.20.0.

The bug is here:

form/packages/form-core/src/FormApi.ts

Line 1002 in 684dec0

this._formId = opts?.formId ?? crypto.randomUUID()

We need to replace this function with uuid's v4 method: http://npmjs.com/package/uuid

I'm very sick at the moment, but will forward to the team. PRs welcome in the interim

Hi guys, sorry for not anticipating this... I'm working on the next patch for Form Devtools (where the issue was originally created) and I'll have it fixed there.

Should be released today!

[AlemTuzlak]

We've debugged and fixed both the mentioned issues on native, fix coming very soon!

[RobertOstermann]

Awesome, thanks for the quick responses!

I updated to v1.21.2 but I am still seeing the issue. I do see that the source code for v1.21.2 has the issue fixed, but for some reason I am still getting the error after a clean install

[harry-whorlow]

Yeah, there's a conflict in the release. I'm fixing it atm

[harry-whorlow]

@qwezey, just for clarification what is the error, the event listener, or crypto

[qwezey]

@harry-whorlow the error is crypto
