Cannot resolve Bilibili BV ID from input: ${String(kwargs.bv

Error message

Cannot resolve Bilibili BV ID from input: ${String(kwargs.bvid ?? '')}

What it means

An ArgumentError wrapping a failure from resolveBvid: the CLI could not turn the user-supplied input (kwargs.bvid) into a valid Bilibili BV ID. The original error message is attached as the cause, and the raw input is echoed in the message (empty string when undefined).

Solutions

  1. Pass a canonical BV ID like BV1WtAGzYEBm as the positional argument
  2. Check the cause message for the resolver's specific complaint (bad format vs failed network resolution)
  3. Resolve the URL to a BV ID yourself before invoking if using short links
  4. Verify no stray whitespace/characters were copied into the argument

Example fix

// before
bilibili comments "https://b23.tv/abc123"
bilibili comments av170001
// after
bilibili comments BV1WtAGzYEBm
Defensive patterns

Strategy: validation

Validate before calling

const BV_RE = /^BV[0-9A-Za-z]{10}$/;
if (!BV_RE.test(String(bvid ?? '').trim())) {
    throw new Error(`input is not a canonical BV ID: ${bvid}`);
}

Type guard

function isBvid(input) {
    return typeof input === 'string' && /^BV[0-9A-Za-z]{10}$/.test(input.trim());
}

Try / catch

try {
    const rows = await bilibiliComments(input);
} catch (err) {
    if (err instanceof ArgumentError && /Cannot resolve Bilibili BV ID/.test(err.message)) {
        // normalize the URL/input to a BV ID and retry
    } else throw err;
}

Prevention

When it happens

Trigger: Passing something that resolveBvid cannot parse — a malformed BV ID, a full URL variant it doesn't recognize, an AV number when only BV is accepted, or an empty/undefined bvid.

Common situations: Copy-pasting a short link (b23.tv) or mobile URL that the resolver doesn't handle; typos in the BV ID; passing a title or search term instead of an ID; forgetting the positional argument.
