Missing 'valueTextArray' for 'containsAll' operator.

Error message

Missing 'valueTextArray' for 'containsAll' operator.

What it means

OperationalError from buildFilter when operator is 'containsall' but valueTextArray is undefined. Identical mechanics to containsAny but for property.containsAll(...).

Solutions

Provide valueTextArray: { operator: 'containsAll', path: ['tags'], valueTextArray: ['x','y'] }.
Remove the filter unit if no array value exists.
Validate filter structure upstream.

Example fix

// before: { operator: 'containsAll', path: ['tags'] }
// after:  { operator: 'containsAll', path: ['tags'], valueTextArray: ['x','y'] }

Defensive patterns

Strategy: validation

Validate before calling

if (f.operator.toLowerCase() === 'containsall' && (!Array.isArray(f.valueTextArray) || f.valueTextArray.length === 0)) { throw new Error("'containsAll' requires a non-empty valueTextArray"); }

Type guard

function isContainsAllComplete(f: WeaviateFilterUnit): f is WeaviateFilterUnit & { valueTextArray: string[] } { return f.operator.toLowerCase() === 'containsall' && Array.isArray(f.valueTextArray) && f.valueTextArray.every(v => typeof v === 'string'); }

Try / catch

try { buildFilter(unit) } catch (e) { if (/valueTextArray.*containsAll/.test(e.message)) { /* supply array */ } else throw e; }

Prevention

Validate containsAll arrays upstream with the same helper as containsAny.
Refuse to emit a filter unit whose array value resolved to undefined.
Centralize operator→required-field rules in one validator.

When it happens

Trigger: Filter unit { operator: 'containsall', path: [...], /* valueTextArray missing */ } reaches buildFilter.

Common situations: Same as containsAny: expression resolved to undefined, key omitted from JSON, or empty source collection.
