Understanding Supabase Database

Supabase is an open-source backend-as-a-service that provides developers with a suite of tools to build applications quickly. It includes a PostgreSQL database, authentication, storage, and real-time subscriptions, making it a comprehensive solution for modern web and mobile applications. Supabase aims to simplify the development process by offering a scalable and easy-to-use platform.

Identifying the Symptom

When working with Supabase Database, you might encounter an error message stating: "2200L: Not an XML document". This error typically occurs when an operation attempts to process a document as XML, but the document is not in a valid XML format. This can disrupt workflows that rely on XML processing, such as data import/export or API interactions.

Explaining the Issue

What is Error Code 2200L?

Error code 2200L is a PostgreSQL error indicating that the system attempted to parse a non-XML document as XML. This error is specific to operations involving XML data types or functions within the database.

Common Causes

This error often arises from:

  • Incorrectly formatted XML data.
  • Attempting to process JSON or plain text as XML.
  • Errors in data import scripts or queries.

Steps to Fix the Issue

Step 1: Validate Your XML Document

Ensure that the document you are trying to process is a valid XML. You can use online validators such as XMLValidation to check the structure and syntax of your XML document.

Step 2: Adjust Processing Logic

If the document is not XML, modify your application logic to handle the correct data format. For example, if you are working with JSON, ensure that your queries and functions are designed to process JSON data instead.

Step 3: Update Database Queries

Review and update any database queries or functions that assume XML input. Use the appropriate data type functions, such as jsonb functions for JSON data, to prevent similar errors. For example:

SELECT jsonb_pretty(your_json_column) FROM your_table;

Step 4: Test Your Changes

After making the necessary adjustments, test your application to ensure that the error is resolved. Monitor logs and outputs to confirm that the data is processed correctly.
