Error message

third_party_parser_not_supported_in_chat

What it means

Thrown by parseFileWithMineruService when platform.parseFileWithMineru is falsy — i.e. the current runtime has no MinerU integration bound. MinerU is explicitly a Desktop-only feature, so on web or mobile the capability is absent and any non-text file routed to the mineru parser fails here immediately.

Solutions

1. Switch the document parser to a build-supported option ('local' or 'chatbox-ai') in settings, or run on the Desktop build where parseFileWithMineru is bound.
2. If you control the platform shim, register a parseFileWithMineru implementation (or a stub that throws a more specific error) so the guard passes.
3. Gate the parser-config UI so 'mineru' is only selectable when platform.parseFileWithMineru is truthy, preventing users from picking an unsupported option.

Example fix

// before
if (!platform.parseFileWithMineru) {
  throw new Error('third_party_parser_not_supported_in_chat')
}
// after — fall back to a supported parser instead of hard-failing
if (!platform.parseFileWithMineru) {
  return parseFileWithLocalFallback(file, uniqKey, { forceChatboxAIFallback: true })
}

// Before selecting the mineru parser, confirm the platform supports it.
function mineruIsAvailable(): boolean {
  return Boolean((platform as any).parseFileWithMineru)
}
if (parserConfig.type === 'mineru' && !mineruIsAvailable()) {
  // downgrade to a supported parser or warn the user
}

function isMineruSupported(p: typeof platform): p is typeof platform & { parseFileWithMineru: (f: File, t: string) => Promise<unknown> } {
  return typeof (p as any).parseFileWithMineru === 'function'
}

try {
  return await parseFileWithMineruService(file, uniqKey, apiToken)
} catch (e) {
  if (e instanceof Error && e.message === 'third_party_parser_not_supported_in_chat') {
    return parseFileWithLocalFallback(file, uniqKey, { forceChatboxAIFallback: true })
  }
  throw e
}

When it happens

Trigger: The effective document parser config resolved to type 'mineru' (or a caller invoked parseFileWithMineruService directly) while platform.parseFileWithMineru is undefined. The check runs before any network call, so no MinerU request is attempted.

Common situations: User synced a config (e.g. via settings import) that selects the MinerU parser onto a mobile/web build that doesn't ship the native bridge; running the renderer in a test harness where the platform shim lacks parseFileWithMineru; desktop build variant where the MinerU plugin failed to register.
