.sym file not working with sentry-cli

SDKs
1

I am following https://docs.sentry.io/learn/cli/pdb/ and this happens-

PS C:\Downloads\breakpad-tools-windows\dump_syms.exe CrashpadTest.pdb > CrashpadTest.sym

PS C:\Downloads\sentry-cli-Windows-x86_64.exe --auth-token token upload-dif --no-bin --org orgname --project projname CrashpadTest.sym
> Found 0 debug information files
> No debug debug information files found

PS C:\Downloads\sentry-cli-Windows-x86_64.exe --auth-token token difutil check CrashpadTest.sym
error: Unsupported file

What am I doing wrong?
