Error when creating ActiveDocs using yaml containing date-time format modifier

When Creating new ActiveDocs using toolbox

3scale activedocs create <remote> <activedocs-name> <specification>

using a specification in yaml file that contains a value of type date-time format modifier for e.g.

zonedDataTime:
    format: date-time
    type: string
    example:  2022-05-10T12:20:40-04:00

error occurs ( shown in the toolbox-activedocs-err.log ) and activedocs is not created . 

The string specified for the date-time is valid as per the OpenAPI 3.0 specificiation. The error occurs in YAML.safe_load. The workaround is to use enclose the value in quotes ( either double or single )

zonedDataTime:
    format: date-time
    type: string
    example:  "2022-03-10T12:15:50-04:00"

or

zonedDataTime:
    format: date-time
    type: string
    example: '2022-03-10T12:15:50-04:00'

With the above change, activedocs is created.
