Error message

Bio size exceeds ${MAX_BIO_LENGTH} characters

What it means

saveUserProfile enforces a hard bio length limit: MAX_BIO_LENGTH = 260 characters (apps/meteor/server/meteor-methods/users/saveUserProfile.ts:23). Any bio longer than 260 characters is rejected before Users.setBio runs.

Solutions

  1. Add maxLength={260} plus a live character counter to the bio textarea
  2. Validate length client-side before submit and block (not silently truncate) oversized text
  3. Catch error-bio-size-exceeded and show 'Bio must be 260 characters or fewer'

Example fix

// before
<textarea value={bio} onChange={(e) => setBio(e.target.value)} />

// after
<textarea maxLength={260} value={bio} onChange={(e) => setBio(e.target.value)} />
Defensive patterns

Strategy: validation

Validate before calling

const MAX_BIO_LENGTH = 260;
if (typeof bio === 'string' && bio.length > MAX_BIO_LENGTH) {
  throw new RangeError(`Bio exceeds ${MAX_BIO_LENGTH} characters`);
}

Try / catch

catch (err) {
  if (err instanceof Meteor.Error && err.error === 'error-bio-size-exceeded') {
    showFieldError('bio', 'Bio must be 260 characters or fewer');
  }
}

Prevention

When it happens

Trigger: settings.bio.length > 260 in the saveUserProfile call - e.g. a long pasted 'about me' text submitted from a textarea without a maxLength attribute.

Common situations: Frontends missing a character counter; migrated/imported profile data longer than the limit; third-party clients with a different assumed limit.
