How to query a datasource of type DateTime MY SQL in App Maker?

Question

I am making a server call querying a record using a datetime filter like follows:

query.filters.CreatedDate._greaterThan = new Date('2020-04-20 19:39:56');

CreateDate is type datetime on a mysql database. But when I run this query I get the following error:

Expected Date for filtering by 'CreatedDate'. Error: Expected Date for filtering by 'CreatedDate'. at appStartUp (DashboardServer:77)

I have no idea why is there a type mismatch. I have also tried converting JS datetime to mysql datetime using the following and many other snippets but still I am recieving the same error.

new Date(); d.toISOString().split('T')[0]+' '+d.toTimeString().split(' ')[0];

Any help will be greatly appreciated.
