Assigning multiple variable in Assign message policy

[anarjinary]

I am trying to populate the 'endpoint' variable as below using assign message policy.

Trial A seems to work as expected. - I ran this request to test if the variable {url_deviceInfo} is getting populted or not.

Whereas TrialB throws an error - service unavailable.

Please let me know how to make Trial B work, {url_deviceInfo} is getting populated from KVM.

{url_deviceInfo} contains the hostname:port (eg: xyz.com:1234)

Trial A

<AssignVariable>
        <Name>endpoint2</Name>
        <Value>http://xyz.com/infinity/v1/subscriptions/{url_deviceInfo}/{req.partnerId}/</Value>
    </AssignVariable>

Trial B

<AssignVariable>
        <Name>endpoint2</Name>
        <Value>http://{url_deviceInfo}/infinity/v1/subscriptions/{req.partnerId}/</Value>
    </AssignVariable>

Did you try using the Template option?

<AssignVariable>
        <Name>endpoint2</Name>
        <Template>http://{url_deviceInfo}/infinity/v1/subscriptions/{req.partnerId}/</Template>
    </AssignVariable>

<Value> is used for the literal string value.

hi SIddharth,

We are running on private cloud 4.18.05.00 , I doubt if it is available in that version.

FYI: Trial A was run with <Value> as above, it worked. I have seen couple of cases and it works fine.

Thanks.

The template feature is available from 4.19.x I guess.

I am not sure if <Value> can take/process flow variables.

BTW have you tried with Javascript? context set/get variables should work.
