[Bug]: Errors in VSCode output during FIM

[jhrozek]

Describe the issue

I'm seeing a bunch of these in the vscode output:

2024-12-17 21:45:03.489 [error] [streamChoices] Error parsing JSON stream data 102
2024-12-17 21:45:03.489 [error] [streamChoices] Error parsing JSON stream data 
2024-12-17 21:45:03.490 [error] [streamChoices] Error parsing JSON stream data 108

2024-12-17 21:45:03.527 [error] [streamChoices] Error parsing JSON stream data 118

these look like we are not properly streaming the length of the SSE chunks. Everything seems to work though.
