Getting error - py4j.protocol.Py4JJavaError: An error occurred while calling o115.save - apache-spark

Question

Have a pyspark code which is running succesfully as per scehdule every month. It failed this month; we have not made any changes to the code or the configuration. Have looked at all the similar threads but one seems to help.
Any suggestions are greatly appreciated!
