Latest release broken on Obsidian Mobile

[jloh]

Thanks for MetaEdit! I use it a lot in scripts and other places through QuickAdd and its fantastic.

The latest round of updates to fix the plugin with 1.4.x have unfortunately broken MetaEdit on mobile for me with an error only saying:

right side of assignment cannot be destructed

Any hints on how I can help to debug this at all?

I'm running Obsidian's TestFlight edition on iOS which is according to the about page 1.4.7 (106) API version v.1.3.7.

Reverting back to MetaEdit 1.8.0 fixes the problem for me but this means its broken on desktop.

I ran into this issue after setting up a number of buttons to edit my metadata more easily on mobile. For the time being I patched this in my local version. If you open .obsidian\plugins\metaedit\main.js and search for frontmatterPosition you can try to manually apply the fix in #100 which should look something like this (also has a fix to remove the trailing blank line that's showing up for me):
