Hi, I have a question error moralis-v1 [react native]

Hello, I have this error that I get when configuring a new project with expo, I have read several solutions applied apparently from webpack 5 and nothing, I run the project but when compiling to production it does not do it due to the errors. I attach the error and the package

Hi @davidzuccarini

It might not be related to v1-sdk. Do you have any dependency that uses @toruslabs module?

#3

if it comes from moralis-v1 or from a sublibrary of moralis, which when I install only react-moralis I get the error of installing moralis-v1 and when installing moralis-v1 all the errors mentioned above appear, the dependencies that I have are above in the package.

error if I don’t have moralis-v1 installed:

ERROR in ./node_modules/react-moralis/lib/index.esm.js 3:0-39
Module not found: Error: Can't resolve 'moralis-v1' in 'C:\Users\david\Documents\Programacion\React_Native\templateTest\node_modules\react-moralis\lib'

web compiled with 1 error

Can you try the solution from the below GitHub issue? In case if you haven’t already tried.

#5

i try that solution didn’t work for me. I don’t know what else I could do. do i share the repo? the error is in web3auth in expo Webpack 5 Polyfills Issue

Hey @davidzuccarini,

I recommend that you do not use moralis-v1 for React Native any further as the software was deprecated and it was in alpha stage, meaning it was not fully production ready like the JS/React SDK (that is also has been deprecated).

On further note, looks like from your error, your issue is on different webpack versions. I suggest that you look into overriding solution such as react-app-rewired to set the webpack version of your project to v5.

Thanks for the information, I understand, should I use react-moralis? If so, the library I use is react-moralis but when installing react moralis it asks me to install moralis-v1
