Parameter validation error results in code 'unknown' instead of 'validation'

[zspiler]

I'm trying to implement error handling based on error.code.

It seems that in Seedance's case, error related to invalid parameters results in error code 'unknown' instead of 'validation'.

Example

const [result] = await client.run({
    model: 'bytedance:seed-audio@1.0',
    positivePrompt: 'Generate a voiceover for the following text: "Hello, how are you?"',
    inputs: {
      referenceImages: [
        '<some_image_url>`,
      ],
      referenceAudios: ['<some_audio_url>'],
    },
  })

produces error

RunwareError: Parameter conflict detected. Only 1 allowed together: 'inputs.referenceAudios', 'inputs.referenceImages'.
  retryable: false,
  parameter: "[inputs][referenceImages]",
  taskType: "audioInference",
  taskUUID: "dceee9a4-cd61-44fe-afa8-1bf517236138",
  documentation: "https://runware.ai/docs/models/bytedance-seed-audio-1-0#request-[inputs][referenceimages]",
  statusCode: 400,
  code: "unknown"

Cause

Seems that in above case

1. API returns code parameterConflict
2. In deriveCode, parameterConflict is not classified validation

Function deriveCode does classify as validation if || raw.startsWith('conflict'), so could something like endsWith('Conflict') be added?
