Posting content SSE conform with bentoml

[bilaljo]

Hello,

So far, I have found that it is quite easy to realise streaming in Bentoml while yielding the outputs. However, I am wondering how I could achieve this SSE-conformant streaming, i.e. how it sends the JSON in style.

data: some_data\n\n

Simply building this as a string didn't work as it was not a valid base model. I have seen older pull requests on this topic where it was achieved with runners, but I have since found that this is already outdated.

Thanks in advance.
