Unable to copy default metadata schema in AEM Assets

[Mario248]

When I try to create my own metadata schema from the default metadata schema form, I get the following error message

 

I checked the crxde for the same and I dont see default metadata scheme form. I thought it could be related to permission but I have full admin rights.

 Can anyone tell me what could be the issue?

Can you share url where you are trying to create and copy default schema. As for the default schema node in crxde under /conf is not present unless you want to override default schema itself. so , there seems no issue from crxde perspective.Is it cloud?

Also , is it on a specific env as this works absolutely fine on few env I've checked.
