I'm coming across the following issue while deploying one of our custom solutions (managed) as an upgrade to one of our environments.
'Can't import the solution Welzorg: Solution Upgrade action failed after import as holding. InnerException is: This solution cannot be uninstalled because the 'Attribute' with id '860aea4d-ae71-4b62-b55c-b9fb6d13f226(flm_welzorgdistrictid)' is required by the 'Welzorg_Upgrade' solution. Uninstall the Welzorg_Upgrade solution and try again..'
We have been struggling with this issue for the last week, and I can't figure out how to fix it. What I understand from the error message is that the temporary Welzorg_Upgrade solution can't be uninstalled, due to a dependency to the field flm_welzorgdistrictid, so i have to manually uninstall the solution, which succeeds but makes no sense since the automatic import process fails at this..
In our source environment, the Welzorg solution does contain the field flm_welzorgdistrictid, the entity relationship is present in the solution and the field is present on the form that it is supposed to be on.
This field also already exists in our target environment and the dependencies in both environments for the field are the same.
Any help on this matter would be much appreciated.
