xplm_Init_Invalid

"1"

The provided argument was invalid. This can be returned if the provided string is not a valid json string. This error can also be returned if one or more of the provided arguments is invalid, such as a missing required field or an unrecognized parameter such as an unknown runway name. Invalid errors imply that your calling code is generating incorrect JSON and should be fixed; use your plugin's error callback to find more detailed information about the problem with your input.
