flet build - No file or variants found for asset: app/app.zip.hash #2507

Description I wanted to publish static website, I succeeded using this command: flet publish . However flet build web command caused an error: No file or variants found for asset: app/app.zip.hash - I checked that app folder was generated. Could it be problem with hash decoding?
