Call to the white rest service

[Oiligriv]

Hello
when I call a hosted rest service, a blank page appears, from the Browser debug the answer is 200

I have checked both the Datastore from the Server Manager and from the command line and everything seems to be ok

the response

{"error":{"code":500,"message":"Service Hosted/RI01/MapServer not found ","details":[]}}

After making some updates, the service is available again.
