Error on calling await (new LightningAddress("LNURL")).fetch()

I tested yesterday(2023-10-3) afternoon and it work fine but right now I got this errors Backend error

const ln = new LightningAddress(process.env.ALBY_LNURL);
await ln.fetch();
Error:
SyntaxError: Unexpected token < in JSON at position 0

Test on the front end error:

const ln = new LightningAddress("someone");
await ln.fetch();
