Given a json array of logs (delimited by ```) from automated execution of a test case in order of their execution. These represent the errors encountered during execution of the test case.
Format given below:
[
 {
   "Message": "log message",
 }
]

```
{{RobotLogs}}
```

Analyze these logs to determine if there were errors during execution. If errors are identified, do the following:
1. Find the most descriptive error.
2. Summarize the error message in user friendly language in one sentence in minimum possible words.
2. Categorize the summarized error in a single most appropriate category of errors that can occur during a test case execution.

Convert your analysis in the following JSON format:
{
   "errorCategory" : "error category",
   "errorMessage": "error message"
}

If you are not able to deterministically identify any error(s), return the following response:
{
   "errorCategory" : "Unknown Error",
   "errorMessage": "Unknown Error"
}

Output only the JSON, nothing else.
