Failing Vercel deploy with error TypeError: Cannot read property ‘split’ of undefined at multiple objects

I’m trying to deploy my webapp for the first time and I’m getting this error on Vercel:

TypeError: Cannot read property ‘split’ of undefined
at Object.3qS3 (/vercel/path0/.next/serverless/pages/[collection]/[templateId].js:2510:16)

I’m recieving the error regarding multiple objects. I believe this is what’s causing the issue:

  const balanceAmount = parseFloat(
    currentUserBalance.split(' ')[0].replace(/[,]/g, '')
  );

I don’t understand what’s causing the issue.
