Problem#

Each project is limited to 20 serverless indexes. Trying to create more than 20 serverless indexes in a project raises the following 403 (FORBIDDEN) error:

This project already contains 20 serverless indexes, the maximum per project. 
Delete any unused indexes and try again, or create a new project for more serverless indexes. 
For additional help, please contact support@pinecone.io.

Solution#

Delete any unused serverless indexes in the project and try again, or create a new project to hold additional serverless indexes.

Also consider using namespaces to partition vectors of the same dimensionality within a single index. Namespaces can help speed up queries as well as comply with multitenancy requirements.
