FTP Python 550 Parameter Incorrect Filename Error

I'm using ftplib on Python to upload an image. Everything was working fine until it started giving me this error:

ftplib.error_perm: 550 The parameter is incorrect.

Here is the code:

    fileNameA = "2020-04-08_00:15.png" # This one gives the error
    fileNameB = "test.png" # This one works well

    cmd = "STOR " + fileName

    f.storbinary(cmd, file)

When it attempts to upload the file using the first name (generated) it gives the error. However, if I just use test.png it works well.

Any help would be appreciated. Thank you!

Solution

  • Most of the time when using filenames with ftplib, the error is caused because of the :. Change them to underscores, and it should work correctly.

    From

    fileNameA = "2020-04-08_00:15.png"

    to

    fileNameA = "2020-04-08_00_15.png"
