Uploading mask file with invalid masks is not rejected #74

Closed alpatron closed 1 year ago

alpatron commented 1 year ago

Hi, when I try to upload a mask file which contains invalid masks (for example ?:?*?=?)), then Webadmin does not reject this and accepts this file.

The Add Job UI properly rejects this.

Seems the regex here does not properly validate masks.
