read a text file from S3 into a Spark df : UsupportedOperationException - apache-spark

Question

I am trying to read a text file from on-prem s3 compatible object storage using Spark and I am getting an error stating: UsupportedOperationException. I am unsure what this is pointing to and have tried to adjust code thinking maybe it was the spark.read command. I have tried read.text and read.csv both of which should work, but result in the same error. Full stack trace is below along with code:
Code being used:
from pyspark.sql import SparkSession
spark = SparkSession.builder \
.appName("s3reader") \
.getOrCreate()\
sc = spark.sparkContext
sc._jsc.hadoopConfiguration().set("fs.s3a.path.style.access", "true")
sc._jsc.hadoopConfiguration().set("fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem")
sc._jsc.hadoopConfiguration().set("fs.s3a.access.key","xxxxxxxxxxxx")
sc._jsc.hadoopConfiguration().set("fs.s3a.secret.key", "xxxxxxxxxxxxxx")
sc._jsc.hadoopConfiguration().set("fs.s3a.connection.ssl.enabled", "true")
df = spark.read.text("https://s3a.us-east-1.xxxx.xxxx.xxxx.com/bronze/xxxxxxx/test.txt")
print(df)
Stack trace:
