Blitz: Object doesn't support property or method 'fromEntries' in Microsoft Edge 44.19041.423.0

What is the problem?

Missing polyfill for fromEntries in Edge

Steps to Reproduce

When creating a new project (blitz v0.18.0) with auth, navigating to /signup in Microsoft Edge gives the following error :

fromEntries is used here.

I don't know if there's an easy build config we can change for this or if we should use something else instead of fromEntries

[SigurdMW]

Does it really need to be Object.fromEntries and not Object.entries / Object.keys? From the interface it seems like a straight object to me

[flybayer]

@SigurdMW I think .fromEntries is converting the array from .entries back to an object. We could definitely refactor that code to not use .fromEntries and .entries. I simple for loop would work.

[SigurdMW]

Yeah but should it be needed though? Do we handle polyfills in Blitz, or is this handled by next js?

[flybayer]

We currently don't add any polyfills to Blitz, so it would be nice to keep it that way (and rely on whatever Next does)

NextJs issue I think, https://github.com/vercel/next.js/issues/16715

[flybayer]

Thanks @belgattitude! Then we'll let Next.js fix that.

Fixed a few versions ago
