How to add keytool to path??

Please provide the following:

  1. SDK Version:38.0.0
  2. Platforms(Android/iOS/web/all):all

I’m unable to add a custom keystore as I don’t get the prompt to select between expo auto generated keystore or upload my own due to this message…

The keytool utility was not found in your PATH. A new Keystore will be generated on Expo servers…

i have cleared using expo build:android --clear-credentials but I get the same error…
