When mapping attributes between FLC and Vault in coolOrange connector, the same attribute can be mapped to the same attribute more than one time and it is causing an error. It should only be allowed to map an attribute from Vault/FLC to another attribute in Vault/FLC only once.
Which version are you using? If you are using version 1.0 i recommend to update to version 20.0.1 which was just released on the coolOrange Download Zone. Please note that we recommend to uninstall the old version before installing the new version.
Regarding the issue you described i will try to reproduce it and create an issue for it.
An issue was created for this and will be addressed by our development team.
Thank you Manuel, I have tried this with the latest version and same issue.
