Solutions

Use --type post (default) or --type all only
Check spelling and case — the comparison is exact
If other scopes are needed, verify the Nowcoder search API accepts them and update the validation in clis/nowcoder/search.js

Example fix

// before
nowcoder search --query golang --type questions
// after
nowcoder search --query golang --type all

Defensive patterns

Strategy: validation

Validate before calling

const allowed = ['post','all'];
if (!allowed.includes(type)) throw new Error(`--type must be one of ${allowed.join(', ')}`);

Type guard

function isSearchType(v){ return v === 'post' || v === 'all'; }

Try / catch

try { await run(['nowcoder', 'search', '--query', q, '--type', type]); }
catch (e) {
  if (e instanceof ArgumentError && /--type must be all or post/.test(e.message)) {
    type = 'post'; // fall back to default scope and retry
  } else throw e;
}

Prevention

Only use --type post or --type all; watch for plural/typo variants
Note the check is case-sensitive — 'Post' is rejected
Whitelist the type value in wrapper scripts
Consult clis/nowcoder/search.js arg definitions for the canonical enum

When it happens

Trigger: Invoking `nowcoder search --type` with a value other than all/post, e.g. --type user, --type question, --type jobs, or a misspelled value like --type posts (plural).

Common situations: Guessing the valid enum values; copying a --type flag from another CLI; typos such as 'Posts' (case-sensitive check); scripting with a variable that holds an out-of-range scope.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
