[SSISDB].[catalog].[set_object_parameter_value] Cannot find the parameter because it does not exist

What I tried to do:

Sets the value of a parameter in the Integration Services catalog.

EXEC [SSISDB].[catalog].[set_object_parameter_value]

       @object_type=20,

       @parameter_name=N'MyServerName',

       @object_name=N'MyProcess',

       @folder_name= N'MyProcess',

       @project_name= N'MyProcess',

       @value_type=R,

       @parameter_value= N'MyServerName';

GO

Error message:

[SSISDB].[catalog].[set_object_parameter_value] Cannot find the parameter because it does not exist.

Cause and Fix:

Lowercase / Uppercase of the names – environment VS SSIS parameters.

When I set the letters to be exactly the same – it worked.

EXEC [SSISDB].[catalog].[set_object_parameter_value]

       @object_type=20,

       @parameter_name= N'MYSERVERNAME',

       @object_name=N'MyProcess',

       @folder_name= N'MyProcess',

       @project_name= N'MyProcess',

       @value_type=R,

       @parameter_value= N'MYSERVERNAME';

GO
