Dashboard - Project sharing problems

Hi all, I sent a project containing multiple flows in the form of JSON to a colleague, this project also contained a GUI using node-red-dashboard (3.6.0).

Unfortunately once I ran the project the dashboard presented the following message, "please add some ui nodes to your flow and redeploy"

It could not even display new nodes he entered, so he had to delete the entire project to do so.

I redeployed the entire project to him except the flow containing the dashboard nodes and passed this flow to him in text format, at which time it worked.

How come, is it possible to find a better solution?
