I've set up a pyspark session and provided it specific configuration settings based off what I've read:
self.spark_session = SparkSession.builder.appName(
"Example Session"
).config("spark.jars", "../../.jars/spark-bigquery-with-dependencies_2.13-0.28.0.jar")\
.config("spark.hadoop.fs.gs.impl", "com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem")\
.config("spark.driver.extraClassPath", "../../.jars/gcs-connector-hadoop3-latest.jar")\
.config("spark.executor.extraClassPath", "../../.jars/gcs-connector-hadoop3-latest.jar").getOrCreate()
and I'm able to work with the dataset I pull in just fine, transforming the data and the like. It's when I try to write to GCS to eventually write to BigQuery that I get an error:
dataframe.write.format("bigquery").option("temporaryGcsBucket", bucket_path).save(table_name)
The error I receive is:
E py4j.protocol.Py4JJavaError: An error occurred while calling o65.json.

I've looked everywhere but unsure how to resolve this. It looks like I'm missing another .jar file at best guess, but not sure which one.
