Filenames with spaces are truncated by Camunda due to lack of filename encoding on Content-Disposition header

Camunda 7 Topics Discussion & Questions

When uploaded files contain spaces, like “My file.pdf” they are uploaded correctly but then when they are downloaded via cam-file-download directive or a direct call to the res aPI the file is just saved as “My”.

Analyzing the issue I noticed the content-disposition header is malformed, it is set as
“Content-Disposition: attachment; filename=My file.pdf”.

But spaces in filename should be URL encoded, so it shuold be:
“Content-Disposition: attachment; filename=My%20file.pdf”.

Can I have this fixed please?

BTW the solution was not URL encode but to enclose in quotes as per RFC 2231
