wp plugin list: Gives table output but also throws PHP Warning regarding plugin "svg-support"

[porg]

Foreword: I do not know whether this is a bug of wp plugin list or of whether plugin svg-support declared something wrong on which wp plugin list then chokes.

I got an output (table shown redacted below) but also a PHP Warning

$ cd ~/html/apps/myDomain
$ wp plugin list
PHP Warning:  Trying to access array offset on value of type null in /data/web/customer-nr/html/apps/myDomain/wp-content/plugins/svg-support/functions/mime-types.php on line 22
Warning: Trying to access array offset on value of type null in /data/web/customer-nr/html/apps/myDomain/wp-content/plugins/svg-support/functions/mime-types.php on line 22

Closing this

• I now had performed a wp list themes (for the first time as a newbie) and it threw the same error.
  • I then thought: Either this is a bug that both "list" commands of wp-cli have in common.
• Or (and I thought this is more plausible), plugin svg-support has some malformed code.
  • I went to their support forum, and there found it reported.

Sorry for the wrong alarm

• I had performed a DuckDuckGo and a Google search for the error message (with different omissions) but had found nothing.
• Eventually in this specific support forum, searching for "mime-types.php" yielded a result.
• About two weeks old. Maybe the web spiders did not yet pick it up.
