Installation of missing plugins fails

[dwhoban]

Description

I am building a new version of an existing site. After activating the Existing license (Pro) the plugin screen shows the "missing" plugins related to that account. Installation is currently failing.

Steps to reproduce

1. Add license.key to ./config folder
2. Reactivate Pro license
3. Navigate to Settings > Plugins
4. Click on settings dropdown and select Install fo missing plugin.

Additional info

• Craft version: 3.1.22
• PHP version: 7.2.14
• Database driver & version: 15.1 Distrib 10.3.14-MariaDB
• Plugins & versions: none

Also when clicking "Install" from the plugin store, the license key for that plugin disappears and needs to be re-typed into the field

Thanks for reporting @dwhoban. Already fixed for the next release, but it was caught without a GH issue for it, so the release note is now linking here in case anyone wants more context.
