Heads up! If you’re building an integration, there’s a nasty bug in Vector Store management you need to be aware of. Last week, we created around 5 vectors stores using the UI and then around 15 vector stores through the API. We decided to delete the 15 API created stores using the UI, one by one…

This should be fixed now! We saw the issue on the vector store dashboard too, deployed a fix, and is no longer seeing the error. Can you go and try the vector store dashboard again to see if works?

Serious Vector Store bug!
