Issue:

When calling a FlexiCapture API method in the code, an error message throws: "SOAP Server Application Faulted: Invalid parameter value".

Answer:

This error usually occurs when you pass an incorrect value to the method's arguments.

For example, let's say you would like to open the project by calling the method OpenProject(sessionId, projectGuid), however, you pass in an invalid sessionId (let's say you set its value to 0):

Then it will throw the error.  So check and make sure the arguments are valid.
