I have multiple nft. i want make this dynamic(Load nft). can anyone please guide me how to do that. my main feature will be load multiple nft dynamically and once marker found it will redirect to new URL with a id

This looks like it could be a dev server issue. the Uncaught (in promise) [...] is not valid JSON message implies that a JSON file is being served as html (probably a 404) instead of proper JSON.

but this error appear when i init

[neiltron]

I might be wrong but it looks like it's trying to load config.json when you call init. That is, if you call init and the browser can't find config.json, then it might throw that error.

Can you please help me to provide a example/instruction of how to load multiple nft using react typescript.
