QuickFix: "Value cannot be null. Parameter name: proxy" in DIXF

Problem: After creating a new data entity and refreshing the entity list, the new entity doesn’t appear in DIXF data entity list. Interestingly, no errors are encountered when compiling the project. However, the following error message was received when trying to add the data entity in list manually. 

Value cannot be null. Parameter name: proxy

Possible Reason: While building your project or solution exclusively, your code may not exhibit any issues. However, inspect the output window messages in Visual Studio to identify any error messages originating from objects not included in your code.

Proposed Solution: Attempt to build the entire model and rectify any errors. Upon successful build, perform a database synchronization and try again. You should then be able to view new entities after refreshing or manually add them to the list.

ExFlow installation CMD screen

It’s crucial to ensure that the Package zip file is unblocked before extracting it. If it’s blocked, the AXUpdateInstaller won’t be able to access the files even after they are extracted.

To verify this, one can right-click on any file in the extracted package folder, go to Properties, and look for the Unblock checkbox. If it’s unchecked, it means the file is still blocked.

This is a valuable tip for anyone working with zip files and encountering issues with the AXUpdateInstaller.

Just before extracting the zip file, right-click on it > Properties and tick Unblock. and try again.
