Netlify-cms: "fields names must be unique" with 2.10.50, no change in config.yml

[matteocargnelutti]

Describe the bug
Trying to access [url].netlify.app/admin/ using the latest version of Netlify CMS _(2.10.50)_ yields the following error:

Error loading the CMS configuration
Config Errors:
'collections[1].files[8].fields' fields names must be unique
Check your config.yml file.

• config.yml hasn't changed
• The issue only arises when using Netlify CMS 2.10.50
• Reverting to Netlify CMS 2.10.49 fixes the issue.

To Reproduce
I unfortunately can't provide the config.yml in question.

Screenshots

Applicable Versions:

• netlify-cms 2.10.50
• netlify-cms-core 2.28.0
• netlify-cms-app 2.12.14

Hi @matteocargnelutti, can you share your full config.yml?
This is not a bug, but a new schema validation that was not checked previously - duplicate field names under the same collection will result in losing that information when the entry is persisted.

Got it ! Turned out there was indeed a duplicate there, from a merge conflict resolution.

Thanks a lot and sorry for the noise 👍

I'm glad the new validation is already paying off!
