"No code available" when using manual configuration in Sb 6.5.10 and Vue 2.6.14

[josedialpad]

Describe the bug
Using Vue CLI v5.0.8 to create a Vue2 project, running the npm7 migration, and setting up the manual configuration for webpack, the code for the story is not generated and shows "No code available".
Though if switching to another variant in the same story (e.g. from Primary to Secondary) the "Show code" button appears and works as expected.

Additional context
Using the preset configuration, the Show Code button appears and shows the code from the story instead of the result. Switching between stories is the hack that works to show the correct code as it's shown in the video.
