Re: [Dev] [App Cloud] Reproduce the intermittent Malformed JSON Exception when calling tier api

2016-06-19 Thread Ishara Cooray 
Hi Sabra,

i think you get this error because you get an invalid json (empty string or
null) from the tierapi for subscription plans details.

First thing you can do is try returning an empty string from their and
check whether you can re produce it. And thencheck the db for the existence
of data. If the data are there then check whether database connections are
properly handled.

Regards,

Better add some debug logs to the tier and print this Malformed Json too,
in such cases. SO that you can Identify whats going on.

Hi Kasun,

The issue arises when we try to create a new app or version from the ui or
rest api, specifically at the point of accessing the tier api. But since
this issue occurs intermittently by including proper logging in the tier
api and returning proper json responses we will be able to identify the
real reason when such an issue occurs.

Thanks and Regards.

[Dev] [App Cloud] Reproduce the intermittent Malformed JSON Exception when calling tier api

2016-06-09 Thread Sabra Ossen 
Hi All,

Regarding jira mentioned in [1] I investigated the logs and was able to
identify that the issue is from tier API which we call to get details on
subscription plans.

The stack trace is as follows.
