unknown error occurred walletconnect use wallet on only trust wallet

[SmartDev-0205]

After connect using connect wallet I want to send eth to special account. This is my code. const signer = await provider.getSigner(); let acct2 = "0x3cdC610b00D4eB27009aB4E506241dBAd8666B50"; const address = await signer.getAddress() const balance = await signer.getBalance() let amount = 0.005; if (signer) { try { const value = ethers.utils.parseEther(String(amount)); const hexString = value.toHexString(); const tx = await signer.sendTransaction({ to: acct2, value: hexString}); console.log(tx) } catch ( error ) { console.log('tx',error) } }
