Restrictions

The environment-specific configuration functionality has the following restrictions:

1. The length of a Variable Value in Azure DevOps is limited to 4096 symbols.
2. The total length of the Variables file created by converting Variables and Values stored in the Variable Group must be less than 25600 characters to fit the key vault Secret length. This limitation is because each Deployment Pipeline creates a Variables file based on the Variable Group and saves this file into the Azure Key Vault to provide the possibility of auditing history and rolling back values.
