How to fix: Attribute has too few values

The attribute requires multiple values but fewer than the minimum were submitted.

Each product attribute in Google's spec has format and value rules. Issues here are usually: missing required attributes for the category, invalid enum values (e.g., 'XL' submitted where 'M, L, XL' is the valid set), out-of-range numbers, or attributes that conflict across the feed.

1. Look up the affected attribute in Google's product data specification: https://support.google.com/merchants/answer/7052112.
2. Check whether the attribute is REQUIRED (must be set) vs RECOMMENDED (optional but helpful) for your product category.
3. For enum-style attributes (gender, age_group, condition), use ONLY the documented values exactly.
4. For free-text attributes, stay within the character limit and avoid promotional language.
5. Re-upload the feed and check the next processing cycle.

• Submitting 'unisex' for `gender` when the spec only accepts 'male', 'female', or 'unisex' — case matters
• Using 'Adult' instead of 'adult' for age_group — Google's enum check is case-sensitive
