Apigee Integration fails to validate incorrect variable assignments in an integration

## Issue Apigee Integration fails to validate incorrect variable assignments in an integration. For example, you can currently assign a JSON value to an unassigned variable of String data type. This behaviour might cause data mapping and integration failures. Until this issue is resolved, we recommend that you do the following: * Assign values to an integration variable as per the variable data type. * Verify and update existing integration variable values as per its respective variable data type.
