Solutions

1. Trim the bio to 1000 characters or fewer.
2. Set maxlength=1000 on the bio textarea in the UI and show a live counter.
3. Truncate imported bios to the limit.

Example fix

// before
User.create({ username, password, bio: longDescription });
// after
User.create({ username, password, bio: longDescription.slice(0, 1000) });

if (typeof bio === 'string' && bio.length > 1000) bio = bio.slice(0, 1000);

const isBioLengthOk = (b) => typeof b !== 'string' || b.length <= 1000;

When it happens

Trigger: Creating/updating a user with a bio longer than 1000 characters.

Common situations: User pastes a long CV/resume into the bio field. Programmatic profile sync brings an oversized description.
