Fix MongoServerError

✅ Solution

MongoServerError in Payload CMS usually arises from schema validation failures during database operations, like inserting or updating data that violates defined constraints. To fix this, carefully examine your Payload CMS collection schemas, ensuring that data types, required fields, and validation rules (like min/max values for numbers or regex patterns for strings) are correctly defined to match the data being entered. Adjust your schemas or sanitize/validate the incoming data before it hits the database to prevent these violations.
