Issue/Introduction

When we download mar file for baseline testcases in DevTest Portal, very frequent we see, an error has occurred page.

​​​

When issue is replicated can see below error in reshub log:

Environment

Release : 10.6

Component : CA Application Test

Cause

Upon further investigation of the project Bank v5, the issue was found.

There is a _quick_stage_document_.stg  file under "Bank v5/Tests/StagingDocs/".

While downloading the Baseline test mar, DevTest creates the staging file with the same name "_quick_stage_document_.stg" and because of duplicate entry it's failing to download (create a project + archive them in Mar + Stream out to client).

Resolution

If we  rename or remove the file  _quick_stage_document_.stg from "Bank v5/Tests/StagingDocs/" and refreshing the project in Portal, we can download any test MAR without issues.
