STR:

1. Select (TB generated) key in account manager e2ee settings
2. Choose "Export Public Key to File"
3. Choose a target location

Expected result:
The public key file is written

Actual result:
The file isn't written and the erro console contains the following error:

Uncaught (in promise) TypeError: idArrayMinimal is not iterable
    getMultiplePublicKeys chrome://openpgp/content/modules/RNP.jsm:3296
    extractPublicKeys chrome://openpgp/content/modules/keyRing.jsm:580
    openPgpExportPublicKey chrome://messenger/content/am-e2e.js:1360

I see that. From bug 1756015.

Sorry, rather bug 1629309.

Thanks Magnus for the fix, will review shortly.

However, I wonder why I cannot reproduce yet, neither with 102.x nor with 104 daily.
Could it depend on properties of a key?
Could you please point me to a key that triggers this problem?

ok sorry, I was using openpgp key manager (not account settings)
