getBalance() method got error: fetch failed

[blockchainlee]

I tried to use getBalance() method, but I got an error:
Error: failed to get balance of account GAcD...Di9xp: TypeError: fetch failed
I found that I call any method under Connection, I got the same error.

I guess maybe I should use agent, so I change my code to
const connection = new Connection(clusterApiUrl('devnet'), {httpAgent: agent})
But I got another error:

What should I do? Please help me, thanks.
