Running generate forecast on cloned domain ending with error

Hi,

While I was executing the generate forecast in cloned domain. i see below error:

<E 2020Sep15 04:32:46.416> Initialize class should only be created in a simple domain or subdomain.

<E 2020Sep15 04:32:46.418> BatchForecast::initialize: Invalid measure store (domain) type.

<E 2020Sep15 04:32:46.418> Exception thrown during batch forecast - Invalid measure store (domain) type.

<E 2020Sep15 04:32:46.418> Cleaning up.

Not sure why is that so. Another question on the same line. While generating generate.xml from pregenerate it was giving today's date as in the birth but while we generate the forecast on the full domain it was RPAS TODAY but not the current date.
