Site health says

Code:

PHP modules perform most of the tasks on the server that make your site run. Any changes to these must be made by your server administrator.
The WordPress Hosting Team maintains a list of those modules, both recommended and required, in the team handbook (opens in a new tab).
Warning The optional module, bcmath, is not installed, or has been disabled.
Warning The optional module, exif, is not installed, or has been disabled.
Warning The optional module, imagick, is not installed, or has been disabled.
Error The required module, gd, is not installed, or has been disabled.
Background updates ensure that WordPress can auto-update if a security update is released for the version you are currently using.
Error The DISALLOW_FILE_MODS constant is defined and enabled.
Error The AUTOMATIC_UPDATER_DISABLED constant is defined and enabled.
Error A plugin has prevented updates by disabling wp_version_check().

Because a file cannot be written to Heroku's file system, updating and installing plugins or themes should be done locally and then pushed to Heroku.
