currentProjectId
In Langfuse, ProjectID is a hash-like string. It's currently determined by the API keys, no way to change it programmatically. E.g. https://langfuse.com/project/abcde123/traces
In W&B Weave, ProjectID is the same thing as the project name, e.g. https://wandb.ai/weave-entity/project-name Where "project-name" is the project name
