Hi,

Can you please help me out .

How did you configure the Task. Can you post a screenshot of you basic, advanced and authentication configuration? Otherwise it is hard to locate where the issue might be.

Hi Benj Huserben,

Excuse me for the post, As i am new to this forum posted in the another conversation.

As mentioned , i am sharing you the screenshot for your reference.

I have configured as per the details given in ur page. But dont know where am i missing the details .

Please have a look and help me out.

Thanks in Advance.

The build definition that you want to to trigger is called "$(QueueBuildDefinition)" or is this a variable that you defined?

Can you show me as well the output of the task?

[ravikumarjonnadula]

I have defined as variable.

[huserben]

I see you are using the version 1.5.0 can you try it with the newest version (1.11.1), this might be a problem that was fixed already.

[ravikumarjonnadula]

May i know where to change the version.

[huserben]

I assume you are using an on prem TFS and not VSTS? Then i believe you have to download the task again from the website and update it the same way as you initially installed it.

[ravikumarjonnadula]

As Said i have uninstalled and installed the extension .But still i am getting some error, which i dont understand

But again when i got to the build definition step where i have added the Trigger build its not showing the extra step which u have updated which is build configurations.

[huserben]

I need to have a closer look, but i will not manage today.

however the error is different now, it returns 409 and not 400 now and the first request semms to be successfull...

[ravikumarjonnadula]

Yah first one is successful. and now able to see the changes for the latest version for the extension. But still facing the same error ever after couple of changes.

[ravikumarjonnadula]

Found the issue. i was specifying same agent for both the builds in General Tab of Demand which was casuing the error.

[huserben]

Hi @ravikumarjonnadula can you elaborate the problem a bit? I usually just work with one agent and this does not cause any issues, the build should just wait in the queue till the current one is finsihed...

Just for me to understand the problem and that I know if I need to update some documentation.

[huserben]

I will close this issue as no further feedback was provided.

[ravikumarjonnadula]

Hi sorry for late reply.bit busy with work. I was configured one agent for the 2 builds using Build.agentname equals to agentname.when first build triggered it's taking the same agent while triggering the next build, as the same build agent was busy it could nt assign for the triggered build.
