/mvn/packages/{pkg}/{pkg_ver}/rcg returns HTTP code 500

@mir-am this is not actually related to the documentation because when requesting curl https://api.fasten-project.eu/api/mvn/packages/com.google.guava:guava/24.1-jre/rcg I got an HTTP status code 201.

@amottier
Thanks for reporting an issue.
I would assume that the behavior might have changed in recent major changes to the REST API and the documentation is not updated accordingly.
The issue should be investigated further.

Returning an error 500 for such an API is always the sign of a bug for me.

It feels like some packages are badly analyzed or inserted in the DB and would cause a crash of the generation of the call graph.
I remember a long time ago (It's possible I only reported this on gitter) having the following cases for some packages: the very first call was returning a 201 and any following call would return an error 500.

@mir-am now I'm also getting an error 500 with curl https://api.fasten-project.eu/api/mvn/packages/com.google.guava:guava/24.1-jre/rcg Can you take a look on the server side to see if any logs are available?

@amottier
I will investigate the issue ASAP.

Using the provided example above, I could NOT reproduce the issue locally while debugging the REST API in my IDE, i.e., http://localhost:8080/packages/org.jgroups:jgroups/5.1.9.Final/.
The possible explanation for this issue is related to #461. The REST was down because of PSQLException at the time of sending the above request to our production cluster.

[mir-am]

The issue is addressed in #465.

@mir-am I did again a test with: curl https://api.fasten-project.eu/api/mvn/packages/org.jgroups:jgroups/5.1.9.Final/rcg and I'm getting a 500 error code.

Let me know if I can help with the investigation.
