// Creates a list of environmental variables in an API by its ID value.
//
// When creating an environmental variable, it must follow the constraints below:
//
//   - Both JavaScript and VTL templates support environmental variables.
//
//   - Environmental variables are not evaluated before function invocation.
//
//   - Environmental variables only support string values.
//
//   - Any defined value in an environmental variable is considered a string
//     literal and not expanded.
//
//   - Variable evaluations should ideally be performed in the function code.
//
// When creating an environmental variable key-value pair, it must follow the
// additional constraints below:
//
//   - Keys must begin with a letter.
//
//   - Keys must be at least two characters long.
//
//   - Keys can only contain letters, numbers, and the underscore character (_).
//
//   - Values can be up to 512 characters long.
//
//   - You can configure up to 50 key-value pairs in a GraphQL API.
//
// You can create a list of environmental variables by adding it to the
// environmentVariables payload as a list in the format
// {"key1":"value1","key2":"value2", …} . Note that each call of the
// PutGraphqlApiEnvironmentVariables action will result in the overwriting of the
// existing environmental variable list of that API. This means the existing
// environmental variables will be lost. To avoid this, you must include all
// existing and new environmental variables in the list each time you call this
