Issue/Introduction

Trying to add attachment to a multiple attachment field in MUX on a specific project/task. There is already one file added but attachment fails after spinning for a while.

It is possible to add attachments in Classic for the same attachment field or even on other projects. This happens for all file format extensions

In app-ca log there is a generic error:

ERROR 2025-05-20 11:12:33,536 [http-nio-8080-exec-33] ppm.rest (clarity:admin:9904292__36813F6C-9046-420E-AECF-1E9A98707C3A:PPM_REST_API) (fd00c165-0491-4b3e-961a-1efa79ccd84f) com.ca.ppm.rest.exception.APISystemException: Failed to upload attachment.
