Dynamics 365 Finance and Operations Unified Developer Experience (UDE) environment. How to check deployment model errors.

I recently faced errors in the Unified Developer Experience (UDE) environment while trying to deploy a model. However, there were no build errors and my model had no dependencies on other models.

In order to find the root cause of the issue, we should see the log file. 

• Click on the CRM link and open the "Finance and Operations Package Manager".
• Go to "Operation History". (If you want to view all your deployment history, you need to select the "Package" section.)
• Select the failed line with clicking on the "Operation Name".

• Download the "operationlogs.zip" and you will see, what's really happened on the environment.

If you try to open the "Finance and Operations Package Manager", but it gives you an error even if you have the Power Platform Admin role assigned, you need to add yourself to the "System Administrator" role in the PPAC environment.

In order to add yourself to the System Administrator role in the PPAC environment, you need to perform the following steps:

• Go to https://admin.powerplatform.microsoft.com/manage/environments. 
• Click on your environment name to open the details.
• Click "Membership" in the top right corner. 
• If you aren't in the list of Sys admins, click "+Add me" button to add yourself.

After that, you should have access to the "Finance and Operations Package Manager" page.
