#### _ **Product/components** used and **version/fix** level:_ _NaturalOne_ #### _Detailed explanation of the problem:_ I’m new to the NaturalOne, I run the community edition on windows I follow the guide to run the sample project Travel, when I run the upload csv file step, after I click the upload button, it jump to the logon page again, and shows error in TR-SUPP, then I open the TR-SUPP.NSP, it shows an other error. ```auto An error has occurred. See error log for more details. Cannot invoke "org.eclipse.core.resources.IFolder.getFile(String)" because "uiProjectFolder" is null ``` I also try run the NaturalONE on linux, but get the same error. I just run the sample code didn’t change any thing, could you give some advice how to fix this issue? thanks. #### _Error messages / **full error** message screenshot / **log** file:_ ![Screenshot 2026-03-19 095916](https://global.discourse-cdn.com/techcommunity/original/3X/3/6/36627cceead17b12efb5ff7f365022578b5f35f3.png) ```auto An error has occurred.

Hi Jun, When I select a different file than the **expenses\_trip1.csv** or **expenses\_trip2.csv** of the **Expenses** folder, then it also jumps to the logon page, When I select expenses\_trip1.csv, then it works without errors. Which file did you select? When opening the **TR-SUPP.NSP** or the **MG-SUPP.NSP,** I see exactly the exception you attached. Other files I can open without this exception. At a first glance I think it happens, when NaturalONE tries to find the depending objects (Dependency view) of TR-SUPP.NSP and is confused about the names: The filename of the Adapter is **TR-SUPP-**.NS8 (=8 characters). But in the corresponding layout file **travel\_support.xml** the Adapter name is **TR-SUPP-A**. The same inconsistent naming is done in MG-SUPP.NSP. If I close the Dependency view, I can open the TR-SUPP.NSP without error. This means: This looks to me like a problem of the Travel sample. We will check this and - if this is the reason - correct the Travel sample. Best Regards, Christine ---

Hi Christine, I tried both **expenses\_trip1.csv** and **expenses\_trip2.csv** , they both jump to the logn screen when I run it. ---

Hi Jun, Thanks for the screenshots. It looks correct, I cannot see anything wrong. Still the Natural program must have problems reading this file in your environment. I currently don’t know why. Traces would show more information, but this would be some effort also for you. Best Regards, Christine ---
