From the UI, when trying to filter on a value that has a space, an error is returned:

"unauthorized sign in flows request"

A use case would be when defining a subnet label such as "AWS S3 us-east-1", and then filtering on it: it produces an error.

A simple workaround is to not use those forbidden characters when defining subnet labels.

Two options for fixing:

• Either do a validation when creating a subnet label (perhaps that should apply to other fields as well, to be checked), with some forbidden characters matching the regex that is done on the console side
• Or relax the rule on the console side, to allow any values.
