Unable to crawl page using scrapyd-deploy portia spider

[ghost]

Hello, I created a portia spider and downloaded it as scrapy project. I run Windows 10 with docker and scrapyd is running it's service on port 6800 properly. However, when I schedule a spider to run, the following log is displayed: https://pastebin.com/raw/29EU34XM

Using the following commands for scheduling spider:
$ curl http://localhost:6800/schedule.json -d project=myproject -d spider=spidername

Any help would be appreciated. Thanks.
