Cancel api throwing an exception and not cancelling at the end of term.

[Vivek Manpuria (Vivek)]

Dear Team,

Upon calling the "Cancel Subscription API", I have noticed an exception is being thrown, because of which, the cancellation is done immediately instead of at the end-of-term.

Step 1: Call Cancel Subscription API  to cancel at END_OF_TERM 
Step 2: Observe exception in logs, "Exception thrown by subscriber method handleSubscriptionTransition"

Step 3: Subscription is cancelled immediately instead of at END_OF_TERM.

I have attached the KillBill logs for the above steps.

 

Thank you,

Vivek

Hi Vivek,

I checked the attached log as well as tried the cancellation ( with invoice group plugin as well as without it ) and in both cases it worked ok for me. In the logs that were generated, I see the delete call like this but similar seems missing from the log that you shared. All the calls in there point to immediate cancellation. Could you please share the api call that you used as well as full logs. 

DELETE http://localhost:8080/1.0/kb/subscriptions/019eec35-60de-4824-8899-104c107f6f94?callCompletion=false&callTimeoutSec=5&entitlementPolicy=END_OF_TERM&billingPolicy=END_OF_TERM&useRequestedDateForBilling=false

Dear Team

Upon investigating this issue, I found that turning off the invgrp plugin helped resolve the issue, i.e. the exception from Step 2 was not thrown. The invgrp plugin contains code from https://github.com/killbill/killbill-invgrp-demo.git after commenting out some portions. No new code was added.

Thank you,

Vivek

Hi Karan,

Here are the steps to reproduce the issue:

1. Start the demo invgrp plugin

2. Create an account

3. Create a subscription

4. Cancel the subscription (billingPolicy = END_OF_TERM, entitlementPolicy = END_OF_TERM)

5. Cancel the subscription (billingPolicy = IMMEDIATE, entitlementPolicy = IMMEDIATE)

6. Observe "Exception thrown by subscriber method handleSubscriptionTransition" in the logs

When only Steps 2 to 5 are performed, then Step 6 is not observed.

If needed, I can send logs after executing the above steps.

Thank you,

Vivek

Hi Vivek,

I checked the logs. I see the below calls in the log. These are different calls. Are separate calls being issued for End of term and Immediate cancellation?

Hi Karan,

Yes, those are 2 separate calls to cancel the subscription. Both calls are to cancel the same subscription. The first one is an END_OF_TERM cancellation (Step 4). The second one is an IMMEDIATE cacellation (Step 5).

1. Start the demo invgrp plugin

2. Create an account

3. Create a subscription

4. Cancel the subscription (billingPolicy = END_OF_TERM, entitlementPolicy = END_OF_TERM)

5. Cancel the subscription (billingPolicy = IMMEDIATE, entitlementPolicy = IMMEDIATE)

6. Observe "Exception thrown by subscriber method handleSubscriptionTransition" in the logs

Thank you,

Vivek

Hi Karan

I made a change to the demo invgrp plugin and used it. Now, there are no errors. We are good. Thanks.

Thank you,

Vivek
