Hi,

I'm having an issue with opening a custom theme in the Themer:
This is my theme structure:

MyCoreTheme <-- ThirdPartyCoreTheme <-- ThirdPartyTheme <-- MyCustomTheme.

When I try to open a theme (any of above), I get to see this error:

We've tried it on Mac OSX and Windows 7.

Themer: 1.2.0.41

Mac OSX:
Sencha CMD 6.5.0.180
ExtJS 6.5.0

Windows 7:
Sencha CMD 6.5.1.240
ExtJS 6.5.1

This is the log from Mac OSX Sierra:
