How to Resolve the \"ObjectID Required\" Error on Algolia

Algolia serves as the search engine for this blog, and occasionally, I need to add new blog posts. To do this, I download the JSON file through a specific website URL and manually upload it on the Algolia dashboard.

While uploading the JSON file today, I encountered the following error:

Upload error: The 'objectID' attribute is required to use action=updateObject

Upon examining the JSON file in VS Code, I discovered that there was an entry with an empty value for the "objectID" attribute. To resolve this issue, I simply removed the problematic item and successfully completed the upload process.
