Good morning, 

I currently have an application I would like to connect to from outside of the Thinkwise ecosystem.

I have tried browsing to this application using both the id and the alias, to no avail.

All of the required software has been installed. To make sure I also used the following thread: 

I also found this thread: 

This helped me to confirm that the application I am trying to reach is actually found. 

Below also a snippet of the error message that is being logged when trying to interact with the application:

Does anyone have a clue as to what could be my problem here?

Thanks in advance,

Hi,

It could be that the object 'empty_master_import’ exists twice. That could happen if you have a table, task and/or report with the same name as another table, task and/or report. Can you check if that is the case? Be sure to also run all Validations for your project to find any additional errors.

Hope this helps!

@Mark Jongeling Thank you for the reply.

Unfortunately it seems that there is only one ‘empty_master_import’ object. I have also run all validations, and there are no errors which would indicate where my problem is coming from.

I've contacted the Indicium team and they confirm it should have something to do with object names being double; specifically a Task and a Report. Could you check again if that could be the case? It could even be a generated object.

Have you (re)synced the application model to IAM to ensure the application model in SF is the same as in IAM?

It could also be that some SQL-typed Control procedure code adds prefixes to objects and causing this problem although being unlikely :sweat_smile: .

@Mark Jongeling Finally got it working!

Since we couldn't identify the root cause of the problem, we decided to rename the task ‘empty_master_import’. Afterwards, we did a sync to the IAM and the application worked instantly. 

Many thanks for the help!
