I have created a command from check_snmp.
I used it in a service template and a host to test custom fields von OID & Community String.
In the Host i use something simular to “write back” (?).

After that i go back to the command and see:

Uncaught Error: Object of class stdClass could not be converted to string in /usr/share/icingaweb2/modules/director/library/Director/Web/Form/Element/Text.php:14
Stack trace:

#4 /usr/share/icingaweb2/modules/director/library/Director/Web/Form/DirectorObjectForm.php(818): Icinga\Module\Director\Web\Form\DirectorObjectForm->prepareFields()

How can i delete these command?

We build another Command that work as expected.
But we cant change it anymore.

Both commands are now not editable
