Invalid URL scheme when using Chroma and Docker Compose

[habuma]

It's unclear if this is a bug or not (or what is causing it), but it sure feels like a bug.

If I create a brand new Spring Boot app with Docker Compose Support and Chroma, I get a build file that includes the following dependencies:

    developmentOnly 'org.springframework.boot:spring-boot-docker-compose'
    developmentOnly "org.springframework.ai:spring-ai-spring-boot-docker-compose:${springAiVersion}"

And it gives me a nice compose.yml file with all that I need for Docker to start Chroma.

However, once it actually tries to hit the Chroma vector store, I get an exception that is ultimately caused by this:

Caused by: java.net.URISyntaxException: Illegal character in scheme name at index 0: 127.0.0.1:/api/v1/collections/SpringAiCollection

I did a little debugging and found that in ChromaVectorStoreAutoConfiguration when the ChromaApi bean is being created (at https://github.com/spring-projects/spring-ai/blob/main/spring-ai-spring-boot-autoconfigure/src/main/java/org/springframework/ai/autoconfigure/vectorstore/chroma/ChromaVectorStoreAutoConfiguration.java#L66), the chromaUrl is set to "127.0.0.1:8000". But when that is given to the RestClient.Builder in ChromaApi, the "127.0.0.1" is interpreted to be the schema and the "8000" is assigned to the ssp. The host and port are both null.

HOWEVER, if I remove the following dependency from my build, everything works fine and as expected:

developmentOnly "org.springframework.ai:spring-ai-spring-boot-docker-compose:${springAiVersion}"

Clearly something in that dependency is ganking things up. And given that it works fine without it, I wonder why it's put there by the Initializr?
