Could not validate group user data.

Error message

Could not validate group user data.

What it means

GroupsUsersUpdateService::handleValidationErrors throws this ValidationException when the patched GroupsUser entity fails table-level save validation. It wraps the entity and the table so the response includes per-field validation errors (e.g. is_admin, user_id, group_id).

Solutions

1. Inspect the validation errors attached to the response body and fix the offending fields.
2. Ensure is_admin is a boolean and the group user id exists (GET /groups/{id}).
3. Send only schema fields (user_id, is_admin) with correct types.
4. Re-fetch the entity before patching to avoid stale/deleted ids.

Example fix

// before
await passbolt.updateGroupUser(id, { is_admin: 'true' });
// after
await passbolt.updateGroupUser(id, { is_admin: true });

if (typeof payload.is_admin !== 'boolean') throw new TypeError('is_admin must be boolean');

try { await updateGroupUser(id, payload); } catch (e) { console.error(e.body?.errors); /* per-field errors */ }

When it happens

Trigger: PUT /groups/users/{id} with invalid data: is_admin not boolean, unknown group_user id, patching non-existent field, or save() failing on entity rules via patchGroupUserEntity or saveGroupUser.

Common situations: Sending is_admin as string 'true'/1 where strict validation rejects it, referencing a deleted group user, malformed request bodies, API clients not matching schema.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
