I already followed approx. 5 of the common causes and resolutions for this error, but nothing helped as of now, I am unable to create a new space. Did not notice any further error from the frontend as of now. The error I see from the Chrome developer tools is error 500 for https://<domain>/confluence/rest/create-dialog/1.0/space-blueprint/dialog/web-items with the content
{
"errorCode": 500,
"errorType": "UNKNOWN"

Thanks in advance.
