Hello,

I am receiving an error message when uploading a document and I am not sure why.

Here are two bundles that uploaded fine:

But this bundle did not process:

Here is my error:

Here is my upload file module configuration:

The failed filename does not appear to have any illegal characters. Is there anything else that could cause this error when uploading a file?

Thank you

@eric_d_miller one possible reason is having the same name in your folder. Can you check that, please? Otherwise, can you share the inputs from the failed run on your scenario?

@dimitrisgoudis Hello! Do you mean to say that I cannot have a duplicate file name in my destination folder? I do not believe any two files with the same name are being downloaded/uploaded.

I can also confirm that the resulting filename does not exceed 255 characters.

My input bundle on the failed Operation was null '[]'.

Hi @eric_d_miller

To test: Does the upload of file 87 work of you hardcode a filename?

If it works there the filename has some sort of invisible character - you could cleanup the filename with the regexp module.
