SH3008: The target's check found errors, so nothing was exported

Class: operation, exit code 1.

export starts with the target's check, check --target with the target's profile (desktop for windows, linux and macos). That check found at least one error, a frame that doesn't fit the display or a required action with no button, say, so the game wasn't built for it. The message lists each error with the setting it is about.

How to fix it. Fix each error as the message says: check --target <profile> shows the same list, with its warnings. Then export again. Warnings don't stop an export: export-report.json lists them.

For example:

export: error[SH3008]: check --target playdate found errors; nothing was built:
  targets."playdate".frame: the frame (800 × 512) at scale 1 doesn't fit the display (400 × 240)
