In 7.14 the var\_set function in- Canvas no longer accepts the input context as the value. One needs to explicitly set the value now.

Trying to run this expression:  
`date | var_set "mydate" | var "mydate" | render as="debug"`  
gives the error message:  
`[var_set] > args.value is undefined`

To get this to work the value needs to be explicitly set i.e.  
`date | var_set "mydate" value={context} | var "mydate" | render as="debug"`

Hey Mark, apologies for the delay in responding. It does look like that is a bug introduced by some recent updates to the var\_set function. I've let the team know and they're looking into a fix.
