只能选择一个参数: regionCode, id

Error message

只能选择一个参数: regionCode, id

What it means

videoCategories.list accepts either regionCode (categories for a region) or a specific id (a single category). The controller enforces at most one of the two and throws BadRequestException otherwise.

Solutions

Call once with regionCode to list all categories for a region, or once with id to fetch one category — never both
If a category id is known, regionCode is unnecessary; drop it
Validate query composition client-side before sending

Example fix

// before
GET /api/plat/youtube/videoCategories/list?accountId=a&regionCode=US&id=20
// after
GET /api/plat/youtube/videoCategories/list?accountId=a&regionCode=US

Defensive patterns

Strategy: validation

Validate before calling

const filters = { regionCode, id };
const count = Object.values(filters).filter(v => v !== undefined && v !== null && v !== '').length;
if (count > 1) throw new Error('Provide either regionCode or id, not both');

Try / catch

try {
  const cats = await api.get('/plat/youtube/videoCategories/list', { params });
} catch (e) {
  if (e.response?.status === 400 && String(e.response.data?.message).includes('只能选择一个参数')) {
    params = params.id ? { id: params.id } : { regionCode: params.regionCode };
  }
}

Prevention

Use regionCode (e.g. US) to enumerate categories; id to fetch one — pick per use case
Drop regionCode when a specific category id is already known
Validate ISO regionCode format and numeric id before sending

When it happens

Trigger: GET videoCategories/list called with both regionCode=US and id=1 (or id=20).

Common situations: Client merges a region default with a specific category id; spec exploration where both were appended to see behavior; template-based URL builders concatenating all provided options.
