RE: Solution import failed , missing dependencies
Hi,
The first dependency I see for the plugin profiler which developer enable when they want to debug plugin, you can simply remove this solution from your trial environment and then export new solution.
Also as you said you are using a sales trial keep in mind trial mostly have updated solution or version of the solution which is are not present in your company environment. so you can have to follow any of the below:
> Instead of setting up trial setup a sandbox in your company environment and do your changes and move them to prod. There are less changes of the difference but if any you can install updates to your sandbox or prod environment
> If you don't want to do 1st option check which solutions/updates install on your trial and try to install them in your prod it may be from MS or non MS solutions.
