Hi Guys,

Recently, After upgrading from 1.9.1.667 to 1.9.1.703 we’ve started to see this error:

```
Executing stage on agent 'continuaci-01'
Current action : Error expanding action name : Could not expand value 'FinalBuilder [${ProjectFile}]'. The expression "FinalBuilder [${ProjectFile}]" contains errors: Expected closing $ to end the object expression. To use $ as part of a field value, escape it with another $. ie. $$. - "FinalBuilder [$^{ProjectFile}]"

```

This happens when calling FB8 action from within a configuration stage (most our projects do that, as our main deployment logic is 99.9% in FB8)

The error is shown in the “Stage Executing” header of the build details page:

And It is also shown in the log tab when trying to show the expanded name of the final builder project file that’s being run:

Before trying to expand:

After trying to expand:

Under our “FinalBuilder Action” We’re calling our fbp8 project by specifying this path under “Project File” field:  
`$Source.DevOps$/Deployment/FB8/Deployment.fbp8`

There’s no problem with the file actually running - it is running behind the scenes and builds complete as usual, its just that the name is not expanded.

Can you kindly look into this?

Thanks!  
Arik
