When using the jira module to connect to the cloud and attempt to create custom fields via calling:

Help on method create_custom_field in module atlassian.jira:

create_custom_field(name: str, type: str, search_key: Optional[str] = None, description: Optional[str] = None) -> Optional[dict] method of atlassian.jira.Jira instance
    Creates a custom field with the given name and type
    :param name: str - name of the custom field
    :param type: str, like 'com.atlassian.jira.plugin.system.customfieldtypes:textfield'
    :param search_key: str, like above
    :param description: str

The search_key is passed to the REST API by using this key:

        if search_key:
            data["search_key"] = search_key

This does not work sind the cloud rest api requires the key: searcherKey:

Having a quick peek into the REST API of DC the seems to be same there:
