I am trying to pass some form data to my app from a [Code Engine ping subscription](https://cloud.ibm.com/docs/codeengine?topic=codeengine-subscribing-events#eventing-ping-existing-app). In the create command, I have tried different methods to pass the data as part of the POST request, but it resulted in wrong parameters at runtime when the ping event fired.

```
  ibmcloud ce sub ping create -n tweety --destination twitterbot --path /tweet
      --schedule '07 4,8,13,17 * * *' --data 'SECRET_KEY=SET_YOUR_SECRET' 

```

```
  ibmcloud ce sub ping create -n tweety --destination twitterbot --path /tweet
      --schedule '07 4,8,13,17 * * *' --data '{"SECRET_KEY":"SET_YOUR_SECRET"}' 

```

How can I pass the data as regular text data, not as JSON?
