Cannot upload Attachment with file name contain '#'

Hi,
Our project is encountering an issue where we cannot upload an attachment if the file name contains the ‘#’ character; for example, Test# document.pdf.

When attempting the upload, the console and network tabs in the browser display errors, as shown below:

I’m not sure if this counts as a bug or just normal browser behavior. The issue seems to be because ‘#’ is a special character in URLs—anything after it is treated as a fragment, not part of the query parameter.

I would like to confirm whether the a12 team is already aware of this issue.

Thank you.

Hi @anh-round-summit, please check ticket A12-17628, it solves special chars in attachment names.

Thank you @petr-high-peak. Our project now knows the answer.
