Deploy Scrapy project to remote Scrapyd service error - scrapy

Question

I tried to deploy a test Scrapy project to the remote Scrapyd server. I got the following error message in client side.
curl http://IP:6800/addversion.json -d project=test_project -d spider=quotes
{"status": "error", "message": "'version'", "node_name": "serverName"}
Error message in server-side

I checked both client and server sides, the Scrapy version are all 1.5.1. The python version are 2.7.*

The sample curl command you shown earlier is not supposed to work. According to the documentation, you'll also need:
A version argument, which is believed to be the cause of issue you experience now.
A egg argument containing the actual project code, otherwise scrapyd won't be able to receive it when you pass in only the project name and spider name.
