<' not supported between instances of 'str' and 'int' when listing versions

[svenvarkel]

I'm unable to list versions or spiders with error message:

<' not supported between instances of 'str' and 'int'

Same here when trying to run a spider with arguments

212 Simply use ScrapydWeb to deploy your projects, which would generate a meaningful version for you, to be specific, the last modification time of files in your project or your egg file, like '2018-01-01T00_00_01'。

I think this would break automated deployment workflow. Or - is it possible to deploy automatically via ScrapydWeb?

It seems that: versions can only be integers. if you deploy your spider like this: scrapyd-deploy -v 1 scrapyd-deploy -v 2

list versions will work ok

Hi @svenvarkel, @ohenrik , Do you use git versioning in scrapyd-client? Can you share more info like configuration for scrapyd-client scrapyd log and the full message returned by the webservice?

I hit the same bug, I used scrapyd-client deploy <my_project> with scrapy.cfg

...
version = GIT
...

Deployment works fine with 'Statuscode 200' However, listing projects or scheduling projects causes following scrapyd stacktrace
