Mysterious Error when starting a Recipe

[MasterPlexus]

Hi,

since today, when I start a reciepe, there is longer a message stating something like convert input into HTML, and then after some minutes, I receive the following log wich is not clear to me:

ok, it looks like that the dev mode linked to src does not like recipe_specific_options, and the access to that values...

[kovidgoyal]

That error means the DNS resolver failed to rsolve the DNS name fora URL you are trying to open.

[MasterPlexus]

Yes, but the error appears everytime when I try to use

self.issue = self.recipe_specific_options.get('issue')

Where I before had defined

recipe_specific_options = {
    'issue' : {
        'short': 'The Version you want to Download (like 2024/11)',
        'long': 'For example, 2024/07'
    }
}

When I comment it out, then it came back to work.
I'm on 7.21 (in exe and src).

[kovidgoyal]

That will be setting self.issue to None. You need to handle the case of it not being set.

[MasterPlexus]

Hi,

self.issue is set to none in the recipe anyway, and if self.issue is none then the recipe gets the actual issue from the HTML of the current magazine. So i don't think this is the issue.
