[Bug-Candidate]: ParsingError: Type not found struct Checkpoints.Trace208 in Slither Analysis

roisindowling commented 1 week ago

Describe the issue:

When running Slither on our smart contracts, we encounter a ParsingError indicating that the type Checkpoints.Trace208 cannot be found. This prevents Slither from running as expected. Checkpoints.Trace208 is defined in the code and slither was working fine on smart contracts that were using Checkpoints.Trace208 until we added some new smart contracts and increases the size of our repo.

Code example to reproduce the issue:

https://github.com/vechain/vebetterdao-contracts

Version:

0.10.3

Relevant log output:

Hi, can you please confirm if this is an issue on the latest version? I see you are using an older Slither release. Thanks!
