How to Fix MongoDB Error Code – 260 – InvalidResumeToken

MongoDB is a popular NoSQL database that offers high performance, scalability, and flexibility. However, like any software, it can encounter errors that need to be resolved. One such error is the MongoDB Error Code – 260 – InvalidResumeToken. In this article, we will explore what this error means and how to fix it.

Understanding the MongoDB Error Code – 260 – InvalidResumeToken

The InvalidResumeToken error occurs when attempting to resume a change stream using an invalid or expired resume token. Change streams allow applications to listen for changes in a MongoDB collection in real-time. When a change occurs, MongoDB provides a resume token that can be used to continue listening from where it left off.

However, if the resume token is invalid or expired, MongoDB throws the Error Code – 260 – InvalidResumeToken. This can happen due to various reasons, such as:

  • The resume token has expired due to inactivity.
  • The resume token was generated for a different server or replica set.
  • The resume token was not properly stored or retrieved.

Fixing the MongoDB Error Code – 260 – InvalidResumeToken

To fix the InvalidResumeToken error, you can follow these steps:

1. Check the Resume Token

First, verify that the resume token you are using is correct and valid. Ensure that it is not expired and was generated for the same server or replica set you are currently using. If the resume token is incorrect, you will need to obtain a valid one.

2. Generate a New Resume Token

If the resume token is expired or invalid, you can generate a new one by performing a full collection scan. This can be done by using the db.collection.find() method without any filters. For example:

db.collection.find({})

This will return all documents in the collection and generate a new resume token. You can then use this new token to resume the change stream.

3. Store and Retrieve the Resume Token Correctly

Ensure that you are properly storing and retrieving the resume token in your application. The resume token should be stored in a way that allows you to retrieve it when needed, such as in a database or cache. Make sure that you are using the correct resume token when attempting to resume the change stream.

4. Handle Expired Resume Tokens

If you encounter an expired resume token, you can handle it by re-establishing the change stream from the beginning. This means starting a new change stream without using a resume token. While this may result in some duplicate events, it ensures that you do not miss any changes.

Summary

In conclusion, the MongoDB Error Code – 260 – InvalidResumeToken occurs when attempting to resume a change stream using an invalid or expired resume token. To fix this error, you should verify the resume token, generate a new one if necessary, store and retrieve the token correctly, and handle expired tokens appropriately.
