Delta create_checkpoint() breaks Synapse SQL OPENROWSET

[Trebla2010]

After running create_checkpoint(), I'm unable to run OPENROWSET. Getting below error.
I'm running this on Azure Synapse Serverless SQL.

SELECT
TOP 100 *
FROM
OPENROWSET(
BULK 'https://devstoragereporting.dfs.core.windows.net/enriched/TestData/',
FORMAT = 'DELTA'
) AS [result]

Resolving Delta logs on path 'ADLSProcessing/staging/TestData/' failed with error: Cannot parse field field 'parts' in json object.

I found that the file "_last_checkpoint" that gets created into the delta_log folder is what's breaking Synapse SQL. Fortunately, deleting this file restores functionality to my delta table and I keep the performance gain.
What is the purpose of the _last_checkpoint file? Is there a way to prevent this file from being generated?

Below is the content inside the _last_checkpoint file.
{"num_of_add_files":null,"parts":null,"size":132,"size_in_bytes":77024,"version":89}

@Trebla2010 unfortunately this seems like it might be the Synapse SQL delta integration having a bug in how it's handling the Delta protocol

The _last_checkpoint file is an integral part of the protocol, and the parts field is optional, from the linked document:

The number of fragments if the last checkpoint was written in multiple parts. This field is optional.

Sorry if this isn't the answer you were hoping for but our princess is in another castle
