@iqbal-web Why does this fix the issue?

Here's Playground with the blueprint.json currently in the trunk branch:

https://playground.wordpress.net/?blueprint-url=https%3A%2F%2Fraw.githubusercontent.com%2FWordPress%2Fperformance%2Frefs%2Fheads%2Ftrunk%2Fplugins%2Fperformance-lab%2F.wordpress-org%2Fblueprints%2Fblueprint.json

You can see that it loads with Performance lab as expected.

The changes you've introduced here just remove slash escapes, which shouldn't impact the resulting parsed JSON in any way. That said, it would indeed be good to remove those slashes since they aren't needed.

When I load up blueprint.json I see some validation issues in PhpStorm:

I also see validation issues in JSON Schema Validator: https://www.jsonschemavalidator.net/s/smWcDkog

Perhaps this is why WordPress.org isn't showing the Preview button?

Why does this fix the issue?

When exploring wordpress plugins, Gutenberg only has which live preview that is working. So I checked the blueprint JSON file here and found some inconsistencies. So I update it like Gutenberg's current use.

When I load up blueprint.json I see some validation issues in PhpStorm:

Switch my pr, then run the validation. It will be fixed then.

@wordpress/prettier-config WordPress Prettier config enforces unescaped forward slashes
