@sunshiningsoo is this breaking anything?

@tzolov not at all, chroma ApiRouter treats url with trailing "/" same as without. but docs only include without trailing "/"

@sunshiningsoo, after the change did you run successfully all Cohere tests, including the integration tests and auto-config integration tests?

Comment From: sunshiningsoo

@tzolov yes, I've done all tests include readme build section.
