SPrincipal doesn't work when stored in the stable data structures

[saikatdas0790]

This is the error I'm seeing

Panicked at 'Unable to decode: Error { kind: UnexpectedEndOfInput }', /home/saikat/.cargo/registry/src/github.com-1ecc6299db9ec823/ic-stable-memory-0.2.2/./src/primitive/s_unsafe_cell.rs:39:58

Here's the minimal reproduction (same repo, updated code):

Steps to Reproduce error

• dfx start --clean
• dfx deploy --no-wallet
• Open the Candid UI explorer
• Run one of the query methods. No issues
• Run the update method to insert SPrincipal into stable collections
• Run the query method again. Error
• Try the separate methods for String type which has no issues running

Let me know if you need any further details. Thank you

Hello there!
I've updated the library to a new version (0.2.3) - it now contains a fix for this problem.

Thank you very much for reporting it!
