I am getting this error when running a Salesforce scratch org application;

aura_proddebug.js:274 Uncaught (in promise) TypeError: Cannot read property 'Symbol(ViewModel)' of undefined
at getInternalField (aura_proddebug.js:274)
at Object.update (aura_proddebug.js:1793)
at updateCustomElmDefaultHook (aura_proddebug.js:5627)
at Object.update (aura_proddebug.js:5779)

at runWithBoundaryProtection (aura_proddebug.js:8255)
at updateChildrenHook (aura_proddebug.js:5541)
at Object.update (aura_proddebug.js:5751)

Has anyone experienced this before?

I was actually able to spot the issue.

This error has been thrown before in my org when I either didn't have the .html file or I had it with an improper spelling somehow; include case sensitivity on the names.
