Hello @Eugene,
This is probably displayed wrong message on the validation error.
Please make sure that your new Job name does not contain invalid characters in the resource name.
The valid character set in the Job name and other names is: a-z A-Z 0-9 : . - _ and space. Please try to create new Job with these allowed characters.
We need to fix this validation message. Thanks for reporting it.
Best regards,
Marcin Haba (gani)
