@ysalimi are you getting this for every lesson or just some of them?

Hi @mayhew64

I'm getting this error for every lesson.

Kind regards,
Yasser

@ysalimi which version did you download from http://webgoat-war.s3-website-us-east-1.amazonaws.com/ ?

Hello @nbaars,

I've tested :

• webgoat-container-7.1-SNAPSHOT-war-exec.jar
• webgoat-container-7.1-SNAPSHOT.jar

Best regards,

This appears to be related to 'stages' and it also appears to be happening at load time.
@nbaars - I think when we looked before, we spot-clicked and didn't hit any lab stages in the process.

So, I tinkered with some debug statements in Course.java#loadLessonFromPlugin around
if (plugin.getLessonSolution("en").isPresent()) { lesson.setLessonSolutionFileName(plugin.getLessonSolution("en").get().toString()); }
It seems that the lesson solution is not present. Still looking some at it, but you might be quicker on it at this point.

... and this was testing against the self-executing jar in the develop branch

Tested this with the SQL injection lesson which has stages, but in my opinion it works. Only the lesson plan is available for this lesson so there is no lesson solution to show. The messages is indeed correct.
Btw all the GoatHills derived lesson do not have a solution.

Closing this one, we can always reopen this issue.
