Forestadmin-schema.json not updating in development

Yes, looks like it’s not valid indeed !

Error: Parse error on line 4005:
...			"default_value": "<h1>%{platform_name
-----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'

One of my fields has a default value with variables embedded and looks like it breaks :


{
			"field": "email_end_submission",
			"type": "String",
			"default_value": "<h1>%{platform_name} will close in %{days_before_end} day(s) !</h1>

			Your submission is still in progress.

			You can now edit and finalize the application form,
			using this link:

				%
				{
					update_link
				}

			Do not forget to finalize the application when you are done.

			Cheers,
			The Team ",

It’s defined this way in my schema.rb :

t.text "email_end_submission", default: "<h1>%{platform_name} will close in %{days_before_end} day(s) !</h1>\n\nYour submission is still in progress.\n\nYou can now edit and finalize the application form, using this link:\n\n %{update_link}\n\nDo not forget to finalize the application when you are done.\n\nCheers,\nThe Team"
