Cannot read properties of undefined (reading 'prototype')

Moralis General
#1

Since yesterday I have been getting this error, seems to have started when you V2 was launched, not sure why I am getting it:

Uncaught TypeError: Cannot read properties of undefined (reading ‘prototype’)

you can try to use moralis-v1 in case that you are using moralis

#3

yes I saw that
I even uninstalled moralis and react-morlis and reinstalled moralis-v1 and react-morlis I get the same error

#4

what versions do you use?

#5

“react-moralis”: “^1.4.1”,
“moralis-v1”: “^1.11.0”,

#6

Ok so I have a temporary fix
I rolled back to these versions and the problem is gone, so must be something to do with the newer updates

Of cause now I get the annoying update messages / warnings:

707.1822bc18.js:2 Moralis: You are not using the latest version of the SDK. Please update it as soon as possible to enjoy the newest features. Most recent version: 2.0.1

Any way I can remove or disable this?

I don’t know yet a solution for that warning, I also get it in vanilla js

#9

it must be something inside the moralis sdk as I only get it for moralis

#10

it is related to an update that was done yesterday
