Too few arguments

Error message

Too few arguments

What it means

validateArgLength checks the compiled argument array of a query function against its declared min/max arity. If fewer arguments than the minimum are supplied, CompileError 'Too few arguments' is thrown during compileFunction.

Solutions

1. Count the function's required arguments and supply all of them
2. Check that optional arguments you intended to pass aren't being dropped as undefined/null before compiling
3. Consult the function schema (in the compiler's function table) for exact arity
4. If arg count is dynamic, validate length before building the query object

Example fix

// before
{ $cond: [amount > 0] }
// after
{ $cond: [amount > 0, 'credit', 'debit'] }

if (args.filter(a => a !== undefined).length < required) {
  throw new Error(`${fnName} requires ${required} arguments, got ${args.length}`);
}

try {
  compileQuery(query);
} catch (e) {
  if (e.message === 'Too few arguments') {
    console.error('Missing required argument in query function call', { query });
  }
  throw e;
}

When it happens

Trigger: Calling an AQL function like $cond, $substr, or date constructors with fewer positional/named arguments than required, e.g. $cond with 2 args instead of 3, or an empty argument list for a 1-arg function.

Common situations: Hand-written query expressions missing an argument; a query builder that drops null/undefined args so a required slot disappears; copy-pasted expressions with an argument accidentally deleted.
