Bug

What happened:
After I executed the vacuum function, from 0 to 99 json files were deleted from _delta_log directory .
Later when i re-ran dt = DeltaTable(local_path), I get the error in the issue title

What you expected to happen:
import local table successfully

How to reproduce it:
as What happend

More details:

jupyter notebook code

import deltalake
import duckdb
import pyarrow
import pandas as pd

local_price_path = '/Users/watsy0007/resources/test_table'
price_table = deltalake.DeltaTable(local_price_path)
price_ds = price_table.to_pyarrow_dataset()

## compact and vacuum
price_table.optimize.compact()
price_table.vacuum()

and the last operation json as follow

Details

@watsy0007 is there a checkpoint file in the _delta_log directory? Removing all those JSON files is... interesting

[watsy0007]

@rtyler no, this is also the point that confuses me when i read the documentation.
Is is because i am use an early version? maybe from python-v0.12.0.
By the way do I have any other way to fix the data now?

[Blajda]

@watsy0007 did you ever execute cleanup_metadata on the table? Vacuum and Compact should not delete any metadata files.

[watsy0007]

@Blajda sorry, i forgot.
It may have been executed during the initial testing phase after writing data.
I checked the data write time, and the first write happended on October 8th. The delta-rs version is 0.15.0
