/ / Please paste the code text below (do not replace the code with pictures)

async importMember() {
   
    const stream = await this.ctx.getFileStream();
    
    stream.on("data",() =>{
        //  chunk
    })
    
    stream.on("end",() =>{
        //
    })
   
    stream.on("error",()=>{
        //
    })
  }

what result do you expect? What is the error message actually seen?

data event should be executed completely, and the stream event should be triggered after receiving end event. Even if there is an error, the error event should be triggered.

has been looking for a suspected environmental problem all day, and the restriction on nginx has also been opened, but it is still useless.
