I connected to Ragflow's T2S Agent through HTTP requests and constructed a related functional module. Everything worked fine when the module was run (but it was very time-consuming because I couldn't solve the concurrent request problem of Ragflow API). However, when I tried to call this functional module using HTTP requests, an error message 400: Socket hang up was reported.
