Uncaught Error: Can only throw objects

Occasionally, it seems the bing webmaster tools plugin is unable to connect to the bing api (line 303 of class-bing-url-submission-admin-routes.php).

This error returns “Uncaught Error: Can only throw objects” and is not gracefully handled.
At least a few other users have had this same issue:

I can confirm I am not over the daily quota, but even if I was, I think this error could fail silently.

WordPress version 5.7
Current theme: Twenty Nineteen (version 1.9)
Current plugin: Bing Webmaster Url Submission (version 1.0.9)
PHP version 7.3.27
