Bug: UI crashes at start with "undefined (reading 'slice')"

[romainourgorry]

Hello,

I'm running Capacitor version 0.4.2. I tested it from both Brave and Safari browsers, and I have the same behaviour.

When I open the UI it becomes blanks after few seconds and I see this error when I inspect the page:

TypeError: Cannot read properties of undefined (reading 'slice')
    at jr (Kustomization.jsx:107:31)
    at ko (react-dom.production.min.js:167:137)

    at xu (react-dom.production.min.js:280:389)
    at gu (react-dom.production.min.js:280:320)

It seems the issue comes from the line 107 in Kustomization.jsx file:

const url = source.spec.url.slice(source.spec.url.indexOf('@') + 1)

Thank you

I tested it with the version 0.4.0 and I have the same issue

Same here with 0.4.3

Can you try with 0.4.4?
