'Can't activate the expo manifest tools on Visual Studio Code
So I am currently trying to learn React and code on Visual Studio. Now, I am getting errors saying:
Oops, it looks like we couldn't activate the Expo manifest tools: Unable to perform cache refresh for C:\Users\Jasun\AppData\Local\Expo\schema-43.0.0.json: Error: certificate has expired.
Does anyone have any ideas?
Current versions are:
- git version 2.34.1.windows.1
- node version 17.2.0
- expo version 5.0.0
- Visual Studio Version 1.63.0
- yarn version 1.22.17
Solution 1:[1]
reinstall doesn't help for now...
here is the workaround before they fix the issue - "Certificate has expired" when activating the Expo schema
You may try the workaround derived from the issue description
> expo init temp-proj --template expo-template-blank@44
> cd temp-proj
> expo doctor
Once expo doctor executed, the schema-44.0.0.json appear in %AppData%\Local\Expo\schema-44.0.0.json
then you can delete the temp-proj...

Warning: Problem validating app.json: Unable to perform cache refresh for ***C:\Users\Admin\AppData\Local\Expo***schema-44.0.0.json: Error: connect ETIMEDOUT 34.132.55.135:443.
- Find schema-xx-x-x.json in C:\Users\Admin\AppData\Roaming\npm\node_modules\expo-cli\node_modules\xdl\caches
- or search with everything app in your PC
- Paste on C:\Users\Admin\AppData\Local\Expo\
Tadaaa Work

updating your expo cli will fix the issue
npm install -g expo-cli
then check the new version expo --version OR use this link description

I had the same issue. The problem occurs because the file schema-43.0.0.json is missing from the directory.
I fixed it by copying one of the other schemas and renaming it to the missing one.
