Issue with dev server

Hello,

I have created a new Jets app in api mode, and tried to start dev server. It was successfully started:

bundle exec jets server
INFO: You’re missing AWS credentials. Only local services are currently available
=> bundle exec rackup --port 8888 --host 127.0.0.1
Jets booting up in development mode!
INFO: You’re missing AWS credentials. Only local services are currently available

[2021-07-28 18:20:36] INFO WEBrick::HTTPServer#start: pid=83000 port=8888

and after I tried to reach any endpoint I am getting this error
