Window.phantom undefined when using in Nextjs

[ntchungse]

Summary

I am developing a dapp that using phantom to connect. Following docs, I use window.phantom but It's undefined. I also try wallet-adapter library but error WalletNotReady. I already installed phantom wallet and try run another projects Reactjs and it return window.phantom value. Is this a problem with phantom and Nextjs?

Update:
It seems like phantom not working in localhost.

Hello @ntchungse,

Would you mind sharing your code for detecting the provider and establishing a connection?

I am just following the docs https://docs.phantom.app/solana/integrating-phantom

@ntchungse We have a number of dapps using nextjs. And I haven't had any other reports. If you'd like to share your nextjs specific code I can try to repro.
