I keep getting this message when I try to package the problem in polygon :
PackageException: There exists a test where checker crashes.
Why does this error show up?
(I'm using the standard checker that compares sequences of integers)

Probably there is a test where the model solution outputs non-digit characters or the overflow happens.
You can run the invocation of the model solution or use the "preview tests" page in order to find a detailed feedback for each test and find out what's wrong.
I ran my model solution with all my testcase, and nothing is wrong. However, the message still shows.
Also, how do you insert photos to a problem statement.
It happened to me several times, I think it's a bug in Polygon as nothing was wrong. Just build the package once more and it will be successful. If not, write to Mike.
I build the package ~10 times and wasted about 1 hour :(
One more thing you can try is to disable Verify checkbox. We had such troubles with interactive problems — they are not built when Verify is enabled. But standard problems always worked with Verify.
Apparently my packaging for other problems also fail with the same reason. Hope this is just a bug.
It means that there exists such output that your checker fails or returns obiously incorrect result. Say, if output is a single random integer about ~10^18 then expected verdicts are WA/PE (probably, OK if your problem is very unusual).
During verification Polygon uses a predefined set of different outputs to verify that checker returns expected verdicts on each of them.
P.S. Please, write me the problem id in Polygon.
