Hi. I am currently facing an issue with the Dataframe.
I have donwloaded a file from Amazon s3 private bucket and I am facing issues while filtering the rows that respect a certain condition.
Here is my code:
`
//This function allows me to connect to the private s3 bucket
connection();
S3Object s3object = s3client.getObject(bucketName, sourceFile);
DataFrame file = DataFrame.load(s3object.getObjectContent(), FileFormat.CSV);
//listColumns & size displaying
System.out.println(file.getColumnNames().toString());
System.out.println(file.size());
//getting the first line with the header column "AreaQ" being superior to 2
file.select("(AreaQ > 2)").print();`
I am having an error on this last line saying that there was a NULL exception that occured and the exception being "Exception in getValues() with cause = 'NULL' and exception = 'column header name not found 'AreaQ'' de.unknownreality.dataframe.DataFrameRuntimeException: column header name not found 'AreaQ'"
and yet I do have a column named AreaQ with numeric values that are > to 2.
Can you help me please?
