From the Azure console:

- Select Intune
- Select Mobile apps
- Select Apps
- Click Add
- Select Line-of-business app to upload an MSI
- Click App Package File
- Browse for the MSI

Once the MSI is selected, the following fields should be populated:
- Name:
- Platform:
- App version:
- Size:
- MAM Enabled:

But this does not happen and the app configuration cannot proceed.

To resolve the issue, open the MSI with Orca and save a copy of the MSI:

- Install Orca: https://theether.net/download/Microsoft/Utilities/Orca.Msi
- Right click on the affected MSI and select Edit with Orca from the context menu
- Click File | Save As
- Save the MSI with a new name

The upload should now be successful in Intune MDM. It would appear that there are attributes missing from the MSI that are automatically added by Orca on save.
