Answered why this error occurs?

hi guys!

I have something to ask about this error in my error log



this error shows multiple times and this is the only error I found when I visit my error log.
what would be the cause/effect of this error?
what do think I might do to avoid this kind of error


modx 2.2.6 traditional

thanks in advance!

You have a snippet, perhaps getResources, or a plugin that is attempting to make links out of something that it can't. It looks like the field or element that is supposed to supply the resource ID to make the URL with is returning empty, or not returning at all.

That can happen after you (or the installation of an extra) create a new resource but the document map hasn't been updated yet, so snippets like getResources or Wayfinder don't know about the new resource and choke when asked to create a link to it. If that's causing your error, deleting all files in the core/cache directory might clear it up.

thanks susan and bob for the reply

I do not know if it is the problem because I don't have a getresource or a wayfinder extra on my manager.
I think it is in the way on how I create a url.

for example:



this is how I create a url is it bad?

thanks!

thank you very much for your help!
