Given a json array of test step logs (delimited by ```) of manual execution of a test case in order of their execution which were marked failed by user in the format below:
[
 {
   "description": "represents what needs to be done in the manual step",
   "expectedResult": "expected outcome",
   "comment": "represents what actually happened when the step was manual executed. It contains errors seen while running the test case."
 }
]

```
{{TestStepLogs}}
```

Analyze these logs to determine if there were errors during execution. If errors are identified, do the following:
1. Summarize the error in user friendly language in one sentence in minimum possible words.
2. Categorize the error in the most suitable 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.
