Hi @software_developer20 and community members,

Currently I’m trying to develop some small app on plain JS, which suppose to take some data from DHIS (2.40), process it and send to external server. Here is the header

despite I have enlisted destination URL as a CORS whitelist, I still can’t get throw and receiving an error messages:

Access to fetch at ‘https://abc.com/records/batch’ from origin ‘https://bcd.com’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: Redirect is not allowed for a preflight request.

Any suggestions how overcome and resolve this situation? Basically I need to disable
strict-origin-when-cross-origin and be able to get response on preflight stage for POST method.

Thank you very much

Ulanbek
