When analyzing the error log, you can see that there are illegal charactors in your permission.
Caused by: org.wso2.carbon.registry.core.exceptions.RegistryException: The path '/_system/governance/permission/applications/sp3/org.wso2.carbon.identity.application.common.model.ApplicationPermission#12809798' contains one or more illegal characters (~!##;%^*()+={}|\<>"',)
Please check the permission name. Basically those charactors are reserved and have an specific use. So you cannot use them elsewhere whithout encoding them[1].
