Fix SDKError

✅ Solution

The "SDKError" in mistral-client often arises when the error object, potentially containing unhashable types like lists or dictionaries, is used as a key in a dictionary or in a set which requires hashable objects. To fix this, either convert the relevant parts of the error object into hashable types (e.g., tuples instead of lists) or, if the error object itself is being used as a key, extract a unique hashable identifier (like an error code or message string) to use as the key instead. Ensure the corrected code handles potential collisions if using a simple identifier as a key.
