Failed to access file /cascache/cascache/

Hi Team,

I attempted to utilize the swat package to push a pandas dataframe as a Sas table to a Sas server, but I encountered an error message that states "Failed to access cache file." Below is the code that I am executing for your reference. I would highly appreciate your assistance.

Code:

Verify file existence at a designated path

if not os.path.exists(castable_path):
raise ValueError("Unable to locate CASTable at the specified path.")

Transfer CASTable to SAS server

try:
conn.loadactionset("table")
conn.upload(castable_path, casout=dict(name="mytable_1", replace=True, caslib='CASUSER(sasboot)'))
print("CASTable successfully uploaded!")
except swat.CASActionError as e:
print(f"An error occurred while uploading CASTable: {e}")

Please note that I received the following output while running the code:

NOTE: Added action set 'table'.
CASTable uploaded successfully!

ERROR: Failed to access file /cascache/cascache/_f_1e7ad78a_7f7b9bcc1b68.sashdat.
ERROR: The action stopped due to errors.

Start by reproducing the reported conn.upload call with the supplied CASTable path and CASUSER(sasboot) destination, then compare the successful upload message with the later CASActionError for the /cascache/cascache file. Done means identifying whether the failure is in the Python client or the SAS server environment and recording a confirmed fix or guidance.
