inferSchema=true isn't working for csv file reading n Spark Structured Streaming

I'm getting the error message

java.lang.IllegalArgumentException: Schema must be specified when creating a streaming source DataFrame. If some files already exist in the directory, then depending on the file format you may be able to create a static DataFrame on that directory with 'spark.read.load(directory)' and infer schema from it.

when I'm loading the csv file with

spark2
  .readStream
  .format("csv")
  .option("inferSchema", "true")
  .option("header", "true")
  //.schema(schema)
  .option("delimiter", ",")
  .option("maxFilesPerTrigger", 1)
  .csv(path)

and I have tried another format of the options like

spark2
  .readStream
  .format("csv")
  .option("inferSchema", value = true)
  .option("header", value = true)
  //.schema(schema)
  .option("delimiter", ",")
  .option("maxFilesPerTrigger", 1)
  .csv(path)

I'd like to infer the schema and commented out the explicit schema usage.

The csv file example is below:

what is wrong here, as I follow the options instructions strictly, but how infer occurs?

You have 2 options here:

1. Before running the streaming query, write once a sample of your data into your destination. When you will run the streaming query again, the schema will be inferred.
2. Set spark.sql.streaming.schemaInference to true:

spark.sql("set spark.sql.streaming.schemaInference=true")

From the docs:

By default, Structured Streaming from file based sources requires you to specify the schema, rather than rely on Spark to infer it automatically. This restriction ensures a consistent schema will be used for the streaming query, even in the case of failures. For ad-hoc use cases, you can reenable schema inference by setting spark.sql.streaming.schemaInference to true.
