if it worked yesterday why it should not work today? the csv is static does not changes. Also, I tried to put the print statement to see if it prints the table name from csv and it does. Moreover, when I run the databricks manually it works perfectly, no error. I get my desired putput so this does not makes sense why its failing. Yesterday I had similar problem, my table names were written some upper case som lower, i changed them all to lower case, uploaded new file and it run perfectly 0 errors. then set the schedule and this morining it failed.
