Custom Data Entity Error - Value cannot be null. Parameter name: proxy

(1) ShareShare

Posted on by 22

Hello,

I've created a custom data entity based on the table WMSOrderTrans. I've added the relevant files to our DevOps repo, run our build pipeline and deployed using the deployable package. If I manually trigger the entity, it works fine (can export as Excel, can export to BYOD). If I schedule an export package that contains the entity, it doesn't execute (just sits on Execution Status: NotRun). If I attempt to delete the export job (that is sitting on status NotRun), then I get the error: Value cannot be null. Parameter name: proxy

I then have an export package I can't delete (because there's existing activity sitting in NotRun which I can't delete). If I go to regenerate mapping of the entity, I also get Value cannot be null. Parameter name: proxy. 

In a previous build, I generated the deployable package through VS on the devbox, then deployed this to our UAT environment (i.e. bypassing the pipeline build). The data entity worked as expected, could be scheduled, etc. This points me to a repo issue but I can't pin it down sinc eI can't find concrete information on the error message? Any ideas? 

I have the same question (0)

    Issue solved.

    If anyone finds a similar issue to this (wherein there's a disparity between behaviour after DevOps build vs. VS build), it's unsurprisingly repo related. In this case our pipeline solution was missing a project referencing the relevant entity's model. Once we added a new project to this solution and referenced the model & rebuilt via pipeline, the result was as expected. Strangely other projects worked fine despite this which is why there were no red flags.
