❓ Question

After the most recent changes on Magic SDK for React Native, I have been able to successfully login on Android. However, whenever I try to perform a web3 call, the following error occurs:

"TypeError: callbackify is not a function. (In 'callbackify(this.provider.request.bind(this.provider))', 'callbackify' is undefined)"

I tried with other providers and it works, so I guess the problem is related somehow with Magic, maybe something similar to the last issue I submitted here (#131).

🌎 Environment

Sorry that I'm super busy with the IOS fix. I'll try to put some resources into the current week.

It seems that the problem appeared when web3.js introduced the use of callbackify on version 1.2.10, however they are managing to surpass this problem on their new version (web3/web3.js#3733).

I am aware that Magic SDK is not supporting the recent versions (@1.3.x) of web3 and therefore, I won't be able to bump web3 to its last version, which solves this "callbackify issue". On the meantime, I downgraded web3.js to 1.2.9 to get the ethereum transactions working.

Thanks! 👍
