Then in Flags section is this info:

Flags:
      --accept-language string   HTTP header indicating client's preferred natural language. (default "en")
      --content string           Content of the record or pattern to retrieve. The string between the two slashes is evaluated as a regular expression. The wildcard form is also supported.
  -h, --help                     help for get-records
      --id ints                  Internal ID(s) of the record(s) to retrieve.
      --is-active                Retrieve only records in the specified state.
      --limit int                Retrieve the first *limit* records or fewer if not enough records. Use -1 for unlimited.   
                                 *Default value* : 50
      --name string              Name of the record or pattern to retrieve. The string between the two slashes is evaluated as a regular expression. The wildcard form is also supported.
      --note string              Note of the record or pattern to retrieve. The string between the two slashes is evaluated as a regular expression. The wildcard form is also supported.
      --offset int               Skip *offset* records from the beginning of the result.
      --order strings            Sort the result by this field and order (ascending or descending). (default [id])
      --ttl min:max              Retrieve only records with the specified TTL. Possible values are either exact value or range min:max. Examples: `300`, `300:`, `:300`, `300:3600`.
      --type strings             Retrieve only records with the specified type(s).
      --zone string              Retrieve only records belonging to the specified zone(s). The string between the two slashes is evaluated as a regular expression. The wildcard form is also supported.
      --zone-type strings        Retrieve only records of the specified zone type(s).

As you can see, there is no --owner flag, although in the schema is this field defined as anyOf. When I try to use --owner flag, an error appears indeed:

Error: unknown flag: --owner

I can use global -q flag as an workaround (-q owner=johndoe), but it sure will be better if the --owner flag was generated properly.

I assume there is a problem with anyOf type maybe? I found this PR https://github.com/danielgtaylor/restish/pull/85 where is future support of anyOf mentioned...
