Daily logs doesn't support RFC3339 as documentation states #161
Description
When invoking the daily logs endpoint, the documentation states that RFC3339 is the expected format:
A start date in RFC 3339 format. This is a date only without an associated time. Example:
2019-06-13
While the example is not aligned with this, neither is runtime execution. The format must be yyyy-MM-dd, otherwise a bad request response is received.
