yarn start failed after upgrading

Created by: Mouaadouk302

i have upgraded react-scripts to v5 and node to v16 & i get error when starting the project knowing that I have reinstalled node_modules.

output : yarn run v1.22.5 $ react-scripts start Failed to compile.

For the selected environment is no default script chunk format available: JSONP Array push can be chosen when 'document' or 'importScripts' is available. CommonJs exports can be chosen when 'require' or node builtins are available. Make sure that your 'browserslist' includes only platforms that support these features or select an appropriate 'target' to allow selecting a chunk format by default. Alternatively specify the 'output.chunkFormat' directly.

error Command failed with exit code 1. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
