Original GitHub issue: https://github.com/deepseek-ai/Janus/issues/208

Is there a reason not to implement a prototype wrapper of the Janus with Sanic framework? A similar torch-based setup worked but here happens the following, without custom code on the nested level where the error comes from:

Main  2025-03-22 15:18:55 +0000 INFO: packages: sanic-routing==23.12.0, sanic-ext==24.12.0
