INVALID_INPUT

INVALID_INPUT

Error message

PRD content is required

What it means

generateBriefFromPrd validates its options before any auth or network work: if prdContent is missing, empty, or whitespace-only it returns an INVALID_INPUT failure result. The library requires actual PRD text because it sends the content to generate a brief.

Solutions

1. Pass the actual PRD text in options.prdContent, not a file path.
2. Verify the PRD file is non-empty before calling (check file size / read result).
3. Trim and validate the content client-side before invoking the API.
4. Fix the read/interpolation bug that produced an empty string.

Example fix

// before
await exportService.generateBriefFromPrd({ prdContent: prdPath });
// after
const prdContent = await fs.readFile(prdPath, 'utf8');
if (!prdContent.trim()) throw new Error('PRD file is empty');
await exportService.generateBriefFromPrd({ prdContent });

if (typeof prdContent !== 'string' || prdContent.trim().length === 0) {
  throw new Error('PRD content is required');
}

function hasPrdContent(o: { prdContent?: string | null }): o is { prdContent: string } {
  return typeof o.prdContent === 'string' && o.prdContent.trim().length > 0;
}

const result = await exportService.generateBriefFromPrd({ prdContent });
if (!result.success && result.error?.code === 'INVALID_INPUT') {
  throw new Error('Provide non-empty PRD text (not a file path)');
}

When it happens

Trigger: Calling generateBriefFromPrd({ prdContent: '' }) or with undefined/null prdContent, or with a string containing only whitespace/newlines.

Common situations: Reading a PRD file that is empty or read failed silently (fs read returned empty string), passing the wrong variable (file path instead of content), or template interpolation producing an empty string.
