          There is no specific limit on the number of environment variables. However, the size of the associated data structure - which includes the variable names, values, and protected flag values - cannot exceed 20 KB. This limit should accommodate most if not all use cases, but if you do exceed it, you will cause an exception (API) with an “Environment: is too large (maximum is 20 KB)” message.

          • (dict) –

            Represents an app’s environment variable.

            • Key (string) –

            • Value (string) –

            • Secure (boolean) –

              (Optional) Whether the variable’s value is returned by the DescribeApps action. To hide an environment variable’s value, set Secure to true. DescribeApps returns *****FILTERED***** instead of the actual value. The default value for Secure is false.
