Invalid channel Id: ${id}

Error message

Invalid channel Id: ${id}

What it means

Thrown as an InvalidParameterError by the CSRC (China Securities Regulatory Commission) route when the provided channel code (id) is not found in the API's channelLevel response. The route calls getLocalList with channelCode=id, then searches the returned channelLevel array for a matching channelCode. If no match is found, channelId is undefined.

Solutions

1. Use a valid channel code from the route description table in the source (e.g., c101971 for administrative penalties, c101972 for market ban decisions)
2. Omit the id parameter to use the default (c101972)
3. Browse www.csrc.gov.cn, navigate to the desired channel, and extract the code from the URL (the part between /csrc/ and /zfxxgk_zdgk.shtml)

Example fix

// before
const channel = channelResponse.results.channelLevel.find((channel) => channel.channelCode === id);
const channelId = channel?.channelId ?? undefined;
if (!channelId) {
    throw new InvalidParameterError(`Invalid channel Id: ${id}`);
}

// This is already well-structured. To improve diagnostics:
if (!channelId) {
    throw new InvalidParameterError(`Invalid channel Id: ${id}. Valid codes are listed at /gov/csrc/zfxxgk_zdgk route documentation.`);
}

const VALID_CHANNEL_IDS = ['c101972', 'c101971', 'c101793', 'c101951', 'c101985', /* ... see route description */];
const { id = 'c101972' } = ctx.req.param();
// Best approach: let the API validate. The InvalidParameterError is the API's response.
// For client-side validation, cross-reference the channel code format:
if (!/^c\d{6}$/.test(id)) {
    throw new InvalidParameterError(`Channel ID must match format cXXXXXX, got: ${id}`);
}

function isValidChannelId(id: string): boolean {
    return /^c\d{6}$/.test(id);
}

When it happens

Trigger: A request to /gov/csrc/zfxxgk_zdgk/:id where :id (default 'c101972') is not a valid channel code in the CSRC system. The API returns results.channelLevel but none of the entries have a channelCode matching the provided id.

Common situations: Typo in the channel code (e.g., 'c10179' instead of 'c101793'); using an outdated channel code that was removed from the CSRC site; guessing a code format; the channel code format changed on the CSRC site.
