## Topics

### Enumeration Cases

[`case invalidResponse(String)`](/documentation/Evaluations/ModelJudgeError/invalidResponse(_:))

The evaluator can’t interpret the model judge’s response as a valid score.

[`case invalidScore(dimension: String, value: String)`](/documentation/Evaluations/ModelJudgeError/invalidScore(dimension:value:))

A scoring dimension returns a value the evaluator can’t parse as a number.

[`case jsonDecodingFailed(response: String, underlying: any Error)`](/documentation/Evaluations/ModelJudgeError/jsonDecodingFailed(response:underlying:))

The evaluator fails to decode the JSON from the model judge’s response.

[`case missingDimension(String, response: String)`](/documentation/Evaluations/ModelJudgeError/missingDimension(_:response:))

The model judge’s response is missing a required scoring dimension.
The first associated value is the name of the missing dimension.

[`case noScaleValues(dimension: String)`](/documentation/Evaluations/ModelJudgeError/noScaleValues(dimension:))

The scoring dimension has no scale values defined.
