OData sample service GWSAMPLE_BASIC returns error when run as fiori launch pad sandbox

[kamranbazmi]

Hello,

I followed instructions in fiori open sap course to create an app using master detail standard template. i followed the wizard. From the Data connection tab, I picked the service "GWSAMPLE_BASIC" and clicked next. on Template Customization tab, I bound following parameters:

App type: SAP Fiori Launchpad Component (optimized for SAP Fiori Launchpad registration)

Data binding (Object)

Object collection: SalesOrderSet

Object collection id: SalesOrderID

Object title: CustomerName

Object numeric attribute: GrossAmount

Object unit of measure: CurrencyCode

Data binding (Line item)

Line item collection: ToLineItems

Line item collection id: ItemPosition

Line item title: ProductID

Line item numeric attribute: GrossAmount

Line item unit of measure: CurrencyCode

At this point the app is created successfully. Now when I tried to test it using sap fiori launchpad sandbox option, a generic error pops up telling me that some technical error occurred. I opened the developer tools and found several lines with the same type of message saying that odata service failed to load. I searched a lot but did not find any similar post. I also sent messages to rac-support@sap.com. Can someone please take a look and provide a solution. Thanks.

Hi Kamran,

I don't find such a request in the error log of ES5.

In order to uniquely identify your request it would be helpful to add the transactionid or the timestamp of the issue.

See my new blog post

Hi Andre,

There is no log showing up under my id: S0009952444 at all. I used t-code: /iwfnd/error_log. This is weird. I tried few times between 9:30 am and 9:45 am EST today as well but with no log.

Hi Andre, I want to share some more information. The same app works fine via single stack. I checked the logs and it did show up there. However with full stack, it is not working and there is no log either. -Kamran

I can confirm, I did not find any log entries with the username you mentioned.

Yes I know you are not getting logs but I think that is the problem. For some reason, in full stack it is not even reaching to ES5 server error logs. However via single stack it worked. See the log screenshot:

Hi,

Did you find any solution for this issue... getting same error on Full Stack.

Thanks,
