Possible solutions

Additional information

The same message appears correctly on an older version of ServicePulse. I compared the network traffic to ServiceControl on both versions, and it looks identical.

There are two calls:

ServicePulse/api/errors/last/7670683f-e09d-d789-4cc0-572280aa34d0
with a 200 response

and

ServicePulse/api/messages/search/e900c065-9aa8-4e2b-be37-d05b87708091/113074851
with a 404 response.

The response from the first call returns something like this:

}

The error was noticed within one endpoint for one message type.
