look at this line. If you try deploying on BSC you'll need to put the router address of pancake swap in. on AVAX you'll need to put that of traderjoe in

Thanks very much, error still persist.

What testnet dex are you using, the only error is from the address.

Currently using remix

Try to deploy with chainide.com...
Is just like remix

With using correct router address, you should be able to deploy in Remix,
