[CONFIFORMS] - Attachments with special characters

[Matěj Mazák]

Hello,

I have been looking over a problem in ConfiForms for confluence. When a user uploads an attachment and we want to send this attachment to a Jira ticket, if the attachment has any special characters (i.e.: czech diacritics í, á, ý, č and so forth) the ticket fails to create with the following error:

JiraStorageException{statusCode=0, message=com.atlassian.sal.api.net.ResponseException: Error communicating with Jira service: Status: 500 with message: and response: 'Got error while saving attachment Sn?mek obrazovky 2025-08-26 100522.png: Got exception while saving attachment in attachment store. Exception: Illegal char at index 8: 59905_Sn?mek obrazovky 2025-08-26 100522.png' Got error while saving attachment Sn?mek obrazovky 2025-08-26 100522.png: Got exception while saving attachment in attachment store.

What I am trying to think about now is how to prevent it (i guess with a validation rule), but the best would be to replaceAccents on the file name. But no matter how I try, I cannot figure out if it is possible to rename an attachment or just parse it somehow to the IFTTT for Jira create ticket function.
