Data collections break tree generation

[hendrikheil]

I'm experiencing an issue where (even after the recent refactor in #91) data collections cause the file tree to break.

I've made a minimal reproduction of the content schema that is causing the issue here: cc1aa9b

It seems that when the files are listed to generate the tree from, studio is currently unable to resolve the source for data collection items.

The browser console prints

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'include')
    at parseSourceBase (source.ts:7:37)
    at generateFsPathFromId (collection.ts:27:21)
    at host.ts:206:28
    at Array.map (<anonymous>)
    at host.ts:204:28
    at async Promise.all (:3000/index 3)
    at async Object.list (host.ts:201:39)
    at async handleDraftUpdate (useTree.ts:102:18)
    at async useTree.ts:118:7
    at async Object.load (useDraftBase.ts:211:5)

and the studio app fails to render any items in the tree.

As far as I can tell the error is caused by this function

studio/src/module/src/runtime/utils/source.ts

Lines 19 to 51 in 75f56ad

	export function getCollectionSourceById(id: string, sources: ResolvedCollectionSource[]) {
	const [_, ...rest] = id.split(/[/:]/)
	const prefixAndPath = rest.join('/')
	const matchedSource = sources.find((source) => {
	const prefix = source.prefix
	if (!prefix) {
	return false
	}
	if (!withLeadingSlash(prefixAndPath).startsWith(prefix)) {
	return false
	}
	let fsPath
	const [fixPart] = source.include.includes('*') ? source.include.split('*') : ['', source.include]
	const fixed = withoutTrailingSlash(withoutLeadingSlash(fixPart || '/'))
	if (fixed === prefix) {
	fsPath = prefixAndPath
	}
	else {
	const path = prefixAndPath.replace(prefix, '')
	fsPath = join(fixed, path)
	}
	const include = minimatch(fsPath, source.include, { dot: true })
	const exclude = source.exclude?.some(exclude => minimatch(fsPath, exclude))
	return include && !exclude
	})
	return matchedSource
	}

as it currently doesnt resolve any data collection items to a collection source.

Can't reproduce as of this commit.

Thanks @larbish !
