Tools/securityadmin.sh fails creating backup

I used to dump configuracion on yaml files for backup purposes but securityadmin.sh started to fail in the audit part I don’t know why:

I tried to disable audit logs on elasticsearch in case it was related but keeps failing with same error. Somebody could help me?
