datalakefileclient.upload_data without overwrite

It seems that I cannot use upload_data without setting the overwrite flag to true. Maybe I am doing something wrong:

file1 = my_file_system_client.get_file_client("path/to/NONEXISTING_file.txt")
file1.upload_data(data) # Trying to upload to a non-existing file
# Raises: azure.core.exceptions.ResourceNotFoundError: (PathNotFound) The specified path does not exist.

file1 = my_file_system_client.get_file_client("path/to/NONEXISTING_file.txt")
file1.upload_data(data, overwrite=True) # Trying to upload to a non-existing file, with overwrite
# Works!

file1 = my_file_system_client.get_file_client("path/to/existing.txt")
file1.upload_data(data) # Trying to upload to a existing file, without overwrite
# Raises: azure.storage.filedatalake._generated.models._models_py3.StorageErrorException: Operation returned an invalid status 'The condition specified using HTTP conditional header(s) is not met.'

file1 = my_file_system_client.get_file_client("path/to/existing.txt")
file1.upload_data(data, overwrite=True) # Trying to upload to a existing file, with overwrite
# Works!
 

If this is the case for everyone, I am questioning the use of the overwrite flag… or at least its default value of False?

is anything happening with this issue? I just ran into it on trying to use azure.storage.filedatalake.

@navba-MSFT I don’t see how the documentation you linked to helps in any way. Yes there is a parameter called overwrite, the problem is the API seems to fail if that parameter isn’t set to True, even if you’re not overwriting. Also none of the errors thrown are suitable for the situation - it should be something that clearly states the cause of the error is trying to overwrite a file that already exists with overwrite set to false (which is not the case here anyway).

Also, experiencing the exact same issue still with the DataLakeFileClient class.
