500 Server Error when creating new variation
I'm getting a 500 Internal Server Error when attempting to create a variation on an existing experiment. All other calls I'm making work fine, just this particular POST request. I'm following instructions on http://developers.optimizely.com/rest. Please help!
I woudl be happy to help you debug this issue! Usually a 500 error is received when the users API token does not have permission to make the changes you are asking to make. If the experiement is already running and the API Token is attached to a user that only has Editor permissions it will throw an error as editors can not edit already running experiements.
This is just one guess however to truely get to the bottom of this if the above is not the problem you can send me the experiement ID you are trying to update and the API call you are making. DO NOT post your API token here however.
