Error 1101 on code surrounded by try/catch

I'm deploying a Nuxt.js application and my pages event handler is being called but somehow seems to just "stop" executing code and I get the Error 1101 message. The reason I say stop is that I've added console.log lines between every single statement to pinpoint what is going on and the entire thing is wrapped in a try catch block but the catch is never being called.

import { SAML } from 'saml-login'

export default defineEventHandler(async (event) => {
    try {
        console.log(1)
        const saml = new SAML()

        console.log(2)
        const options: Parameters<typeof saml.generateAuthenticationUrl>[0] = {
            providerSingleSignOnUrl: 'xxx',
            applicationEntityId: 'xxx',
            applicationCallbackAssertionConsumerServiceUrl: `http${process.env.NODE_ENV === 'production' ? 's' : ''}://${

            }/auth/saml/sp/acs`,
            allowCreate: false,
        }
        console.log(3)
        const redirectUrl = await saml.generateAuthenticationUrl(options)

        console.log(4)

This is what tailing the logs shows:

  "eventTimestamp": 1719317831505,
  "event": {
    "response": {

  },

}

As you can see it stops on console.log(3) but it should show console.log(6) if there was an exception thrown!
