Uncaught exception in /api/v2/meta-tx/systemInfo call about mexa-sdk

[nikhitakale]

Hi @chejazi ,kindly retry now, it will work. 👍🏻

Can you share more details on unhandled exception and what time request was sent?
This endpoint should always be up as we do not have downtime as such.

Thanks for pointing it out, I will wrap this inside try catch

Nodejs output

This is occurring when initializing the sdk:

            const biconomy = new Biconomy(maticProvider, {
              apiKey: "...redacted"
              debug: true
            });
            biconomy.onEvent(biconomy.READY, () => {
              resolve(biconomy);
            }).onEvent(biconomy.ERROR, (error, message) => {
              reject(error);
            });

Right now if I use my nodejs repl I am seeing the error.

const fetch = require("node-fetch");
fetch("https://api.biconomy.io/api/v2/meta-tx/systemInfo?networkId=137").then(console.log)
