call createDataItemSigner error in next.js

[pChao3]

Hello, when I used next.js and installed aoconnect, an error occurred when I tried to sign message using createDataItemSigner.
TypeError: arweaveWallet.signDataItem is not a function
at signer (browser.js:11951:38)
at eval (browser.js:8855:39)

What is the cause of this? and how to fix it ? Thank you

Hey @pChao3 , sorry that you're having issues.

Do you have the ArConnect Extension installed? This is what you use to store your credentials and what exposes the arweaveWallet api.

Hi, @TillaTheHun0, I just want to sign with my local key file, just like running in a node environment, and I don't want to sign through the browser plug-in of ar wallet. Is it not feasible to directly import createDataItemSigner and then pass in the key file in a browser environment? Do I have to use an arconnect extension?
