SAP WebIDE error when deploying to ABAP Repository

Hello Experts,

Previously, whenever I have made changes to one of our Custom Fiori Applications in the SAP WebIDE, I have pushed them to our on-premise system by using the Deploy to SAPUI5 ABAP Repository function. I am currently training someone new on deploying to our repository, and whenever I have them select the same option, an undefined error appears (with the message "The request to retrieve the transports of the selected application has failed with the following error: undefined") and prevents us from continuing to push the changes to our on-premise system. I have checked and the user has the same roles in SU01D that I do in the target system, but while I am able to create a new transport to add the changes to, they continue running into this error. Is there a configuration step that I have missed?

This is what the other user sees when they attempt to deploy:

This is what I see when I attempt to deploy:

Thanks in advance,
