Google Cloud Pub/Sub is a messaging service that allows you to send and receive messages between independent applications. It is designed to provide reliable, asynchronous, and scalable messaging for cloud-based applications. Pub/Sub decouples services that produce events from services that process events, allowing for more flexible and scalable application architectures.
When working with Google Pub/Sub, you might encounter the NOT_FOUND error. This error typically occurs when you attempt to access a resource, such as a topic or subscription, that does not exist. The error message will usually indicate that the specified resource cannot be found.
NOT_FOUND error message when trying to publish or subscribe to a topic.The NOT_FOUND error is a clear indication that the resource you are trying to access does not exist in the specified project. This could be due to a typo in the resource name, the resource being deleted, or attempting to access a resource in the wrong project.
To resolve the NOT_FOUND error, follow these steps:
Ensure that the topic or subscription name you are using is correct. Check for any typos or incorrect casing, as resource names are case-sensitive.
Use the Google Cloud Console or the gcloud command-line tool to verify that the resource exists:
gcloud pubsub topics list
or
gcloud pubsub subscriptions list
Ensure that the topic or subscription you are trying to access is listed.
Make sure you are operating in the correct Google Cloud project. You can set the project using:
gcloud config set project [PROJECT_ID]
Replace [PROJECT_ID] with your actual project ID.
For more information on managing topics and subscriptions, refer to the Google Cloud Pub/Sub documentation. If you continue to experience issues, consider reaching out to Google Cloud Support for further assistance.
