Not able to read files from share drive

[kogads]

I have a job which reads the files based on the file pattern and creates dataset. It was running fine before but started aborting after reading the files from a share drive. Here is the error message.

Unable to generate a node map from fileset /D=/tmpdir/import_tmp_51692fe518d.fs.

Also I ran the job to create the dataset reading a specific file from share drive rather than file pattern. It ran without errors. I am using the File name column when reading the files using file pattern to capture the file names and $APT_IMPORT_PATTERN_USES_FILESET is set to True.
