Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

Vaibhav, have you verified if your Mail Thing is working as expected i.e. are you able to send/receive emails with that? Have you tried testing the SendMessageWithImage?

Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

Sushant, I am facing this error at the time of testing SendMessageWithImage.

Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

Could you share screenshot how you are testing it and the values you are putting in to test the service?

Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

Vaibhav Sharma​,

Is this extension a custom extension or are you using the mail extension downloaded from the ThingWorx marketplace?

Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

Ankit Gupta

It is a custom extension.

Re: Unable to Invoke Service : No service handler defined for service on thing [Test]

I thing I found your problem.

In your service definition, the name "SendMessageWithImage" is not the java method name (SendMessage)

Fix the name, re-import the extension and clean the cache or restart the server, it should work

Regards,

Cyril
