I am trying to add a parameter to my event, but receiving an error "Internal error Please try again later".
I have no registered any parameter yet (0 text and 0 number). After pressing save button I receive following error messages
Internal error. Please try again later. (in the center)
One or more parameters have not been registered. Please try again (in the top right side)
Here is the steps...
- Add the parameter
- Select parameter type "Text"
- After "Save" button click, I'm receiving fallowing error messages
