Error: functions predeploy error: Command terminated with non-zero exit code1

My index.js looks like this

const functions = require('firebase-functions');

// replaces keywords with emoji in the text key of messages

// pushed to /messages

exports.emojify =

    functions.database.ref('/messages/{pushId}/text')

    .onWrite(event => {

        // Database write events include new, modified, or deleted

        // database nodes. All three types of events at the specific

        // database path trigger this cloud function.

        // For this function we only want to emojify new database nodes,

        // so we'll first check to exit out of the function early if

        // this isn't a new message.



        // !event.data.val() is a deleted event

        // event.data.previous.val() is a modified event

        if (!event.data.val() || event.data.previous.val()) {

            console.log(not a new write event);

            return;

        }



        // Now we begin the emoji transformation

        console.log(emojifying!);



        // Get the value from the 'text' key of the message

        const originalText = event.data.val();

        const emojifiedText = emojifyText(originalText);



        // Return a JavaScript Promise to update the database node

        return event.data.ref.set(emojifiedText);

    });



// Returns text with keywords replaced by emoji

// Replacing with the regular expression /.../ig does a case-insensitive

// search (i flag) for all occurrences (g flag) in the string

function emojifyText(text) {

    var emojifiedText = text;

    emojifiedText = emojifiedText.replace(/blolb/ig, :D);

    emojifiedText = emojifiedText.replace(/bcatb/ig, :D(cat));

    return emojifiedText;

}
