Drag and drop Web Client Error - Upload partially completed

Hello everyone,

I have encountered an issue with the drag-and-drop upload feature in M-Files Web Client. I tested several files, and some upload successfully, while others fail.

For example, I have two .xlsx files. One is a simple workbook with only three cells filled in, while the other is a more complex workbook with multiple sheets and a lot more content. The simple file uploads successfully, but the complex one does not. Their sizes are only around 5 KB and 50 KB, respectively, so file size should not be the issue.

I also tried with archive files. I created one archive containing simple documents and another archive containing scripts. The archive with scripts failed to upload as well, even though the size difference was only around 50 KB.

I should also mention that all the files I tested are not corrupted, and they upload successfully in M-Files Desktop Client.

Is there any Web Client configuration that I might be missing? Or does anyone have an idea what could be causing this behavior?

  • I haven't seen this before, and it certainly doesn't sound like expected behaviour.

    It is probably worth opening a support ticket.  If it always fails on the same file then include that.  If there's some combination of steps you're taking that always replicates it then include those too.  The support team will probably guide you through collecting some logs from your browser to hopefully identify what exactly is failing.
