.NET SDK help - {"Error invoking Service for Entity. Internal Server Error. (Code 1110)"}

[jmay1]

Hello,

I wrote a method in my .net sdk that would call a TW Service that creates my Things and assigns them to their networks and populates the non-remote properties. On the SDK side I have a tool that is reading from an excel sheet and creating things in the platform with the excel sheet data by calling that method. There are approximately 1500 things that should be created when the tool is complete. Only about 740 things are created and the rest are getting TW API exceptions that read {"Error invoking Service for Entity. Internal Server Error. (Code 1110)"}.

Do these codes (1110 in my case) mean anything?

Thanks!
Jenna

Where did you see this error message? In the SDK or in the Application Log?

If you saw it in the SDK, it is likely from .Net itself. The Microsoft documentation on this says the following:

ERROR_MEDIA_CHANGED

1110 (0x456)

The media in the drive may have changed.

If it is in the Application log, I will need to do some more digging. Hope this helps!

Hello Jenna,

I also had same issue when I was running tomcat on HTTP. Run your tomcat securely and that will solve this issue.

Steps to run tomcat securely.

1. First stop Tomcat if already running. Open command prompt with admin rights. Go to C:\Program Files\Java\jdk1.8.0_40\bin

2. Type following command: keytool -genkey -alias tomcat -keyalg RSA

C:\Program Files\Java\jdk1.8.0_40\bin>keytool -genkey -alias tomcat -keyalg RSA

It will ask for some details and password. Provide “tomcat” as password.

3. Above executed command will generate “.keystore” file in “C:\Users\bhapanch” folder. Pls note that “bhapanch” is my username. Keystore file will be in respective user’s folder.

4. Copy this “.keystore” file to “C:\Program Files\Apache Software Foundation\Tomcat 8.0\conf” folder.

5. Open server.xml from “C:\Program Files\Apache Software Foundation\Tomcat 8.0\conf” directory for editing.

6. Navigate to line that starts with - <Connector port="8443" protocol="org.apache.coyote.http11 . If it is commented, then uncomment it.

7. Replace connector port line with following line:

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"

               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"

               clientAuth="false" sslProtocol="TLS" keystoreFile="conf/.keystore" keystorePass="tomcat" />

Note that F is capital in  keystoreFile attribute name and P is capital in keystorePass attribute.

Ensure the password “tomcat” is same which you provided during keystore file generation.

8. Now start Tomcat. You are now all set. Open https://127.0.0.1:8443/ from browser. It will ask first time out secured connection. Then you should be able to see tomcat manager screen.

Once that is done, put/update following line SteamSensorClient.cs

            // The uri for connecting to Thingworx

            config.Uri = "wss://127.0.0.1:8443/Thingworx/WS";//args[0];

....

            config.DisableCertValidation = true;

            config.AllowSelfSignedCertificates = true;

My versions:

Tomcat version 8

ThingWorx version 7.1.3-b14
