Deleting more than one custom pack causes console error

[JarrodPo]

If I delete more than one custom pack in a loop I get this error.

foundry.js:16058 TypeError: Cannot read property 'title' of null

async function deleteCompendiums() {
    const packages = ['world'];
    const compendiums = game.packs.entries.filter(r => packages.includes(r.metadata.package));

    for (let i = 0; i < compendiums.length; i++) {
        await compendiums[i].delete();
    }
}

I forgot to note I was creating my compendiums in code, not though the UI, so there is probably something with this api I should have done.

async function createCompendium(name) {
    const nameLowerHypen = name.replace(/\s/g, '-').toLowerCase();

    return await Compendium.create({
        "label": name,
        "entity": "Item",
        "name": nameLowerHypen,
        "path": "packs/" + nameLowerHypen + ".db",
        "system": "swade"
    })
}

Hi, yeah this will happen because the module stores some metadata about the compendiums in order to sort them into folders. I'll see about including this in a future release but for now you should be able to remove the entry that I create programatically using this (it may need to be before your Compendium.delete() not after):

await game.customFolders.compendium.entries.get(packCode).delete();

It tells me that the delete method is undefined.

game.customFolders.compendium.entries.get(packCode).delete()

The CompendiumFolder object does have a delete method, but I'm not trying to delete the whole folder.

game.customFolders.compendium.folders.entries[0].delete()

Ah looks like i forgot to include the delete method for entries. I'm not sure if there is currently a way to programmatically delete compendiums in that case. I'm currently working on getting compendium folders working for 0.8.x, but if i have some time ill modify the testing version and you can test it.
