Explanation: You are probably trying to create a new output connector in the Platform and you are using the connector type Spool and you are encountering this error. This is because you have not entered % into the To property – see Figure 1
- Open the Platform
- Right-click on the new Output Connector and select Settings…
- From the Selected layer dropdown select Production (Physical)
- Make sure your Connector Type is Spool
- Enter % as the To property value
- Click OK
Export, deploy and test!
