Null pointer exception when adding a new user
-
Hi,
I successfully set up MyController on a Raspberry Pi 3 B, connected to MySensors network through MQTT gateway.I'm trying to add a news user for MQTT, just to avoid using admin user in MQTT gateway configuration.
Every time I try to add a new user, I get a null pointer exception.
The complete error log is:2017-11-07 11:57:17,468 ERROR [Acme.Utils.ThreadPool(5)-PooledThread: Acme.Serve.Serve$ServeConnection@1fd0f5d] [org.mycontroller.standalone.api.jaxrs.exception.mappers.ApplicationExceptionMapper:42] ApplicationException, org.jboss.resteasy.spi.ApplicationException: java.lang.NullPointerException: userId at org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:152) at org.jboss.resteasy.core.ResourceMethodInvoker.invokeOnTarget(ResourceMethodInvoker.java:295) at org.jboss.resteasy.core.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:249) at org.jboss.resteasy.core.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:236) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:395) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:202) at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:221) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:56) at org.jboss.resteasy.plugins.server.tjws.TJWSServletDispatcher.service(TJWSServletDispatcher.java:40) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:51) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at Acme.Serve.Serve$ServeConnection.runServlet(Serve.java:2328) at Acme.Serve.Serve$ServeConnection.parseRequest(Serve.java:2282) at Acme.Serve.Serve$ServeConnection.run(Serve.java:2054) at Acme.Utils$ThreadPool$PooledThread.run(Utils.java:1402) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException: userId at org.mycontroller.standalone.api.jaxrs.model.AllowedResources.<init>(AllowedResources.java:33) at org.mycontroller.standalone.api.jaxrs.model.AllowedResources$AllowedResourcesBuilder.build(AllowedResources.java:34) at org.mycontroller.standalone.db.tables.User.getAllowedResources(User.java:86) at org.mycontroller.standalone.db.tables.User.toString(User.java:47) at java.lang.String.valueOf(String.java:2994) at java.lang.StringBuilder.append(StringBuilder.java:131) at com.j256.ormlite.stmt.mapped.MappedCreate.insert(MappedCreate.java:137) at com.j256.ormlite.stmt.StatementExecutor.create(StatementExecutor.java:458) at com.j256.ormlite.dao.BaseDaoImpl.create(BaseDaoImpl.java:328) at org.mycontroller.standalone.db.dao.BaseAbstractDaoImpl.create(BaseAbstractDaoImpl.java:244) at org.mycontroller.standalone.api.jaxrs.model.UserJson.createOrUpdateUser(UserJson.java:74) at org.mycontroller.standalone.api.jaxrs.SecurityHandler.addUser(SecurityHandler.java:184) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:139) ... 15 common frames omitted``` -

I'm using version 1.0.0.Final from https://www.mycontroller.org/#/downloads
It's my first time with MyController, and I'm not really an expert... so please be patient!
Should I move to snapshot version? Is it stable enough for "not so expert" user like me?
What's the easier way to upgrade?Thanks a lot

@daniele steps to upgrade from one version to another version https://forum.mycontroller.org/topic/206/upgrade-to-new-version

Welcome to MyControler
No worries. I will setup locally and verify this. Thank you! -
Hi Daniele, welcome!!
I use the snapshot version for a couple of weeks now, it works like a charm and is very stable......
-
I moved to version 1.1.0 snapshot, but I still have the same issue with user creation.
-
What if you install the snapshot in a new directory with a clean database...
do you still have the issue?It might be that you import a "broken" database.....
-
I built it from scratch, not from a backup of the previous version

for the email addres just add a@b.com if there is no email availableThis error only shows if not all fields are filled.... (at least on my system, using the same version you use..)
seems you can use spaces in the username
