Here is the problem we had :

• Impossible to see beneficiary image entered on the mobile app in the web

Problem :

• As Rest-API is Dockerized we use a volume and we make a LN , we used "insuree_photos_root_path" to define where our images are stored in the BE module. So in our configuration value of insuree_photos_root_path is "/openIMISphone"
• Method _photo_dir do a path.join with this root path + the file dir (coming from the tables value in tblPhotos... I understood that this value comes from tblDefault on the stored procedures insert)
• problem is path.join consider that each new absolute path found as an argument discard all previous argument : "If a path component represents an absolute path, then all previous components joined are discarded and joining continues from the absolute path component."

• So in our case , impossible to have a complete path to load our images in /openIMISphone/Images/Updated/filename. Web returns directly /images/Updates/filename and obviously file is not found.

Solution :
(Seams OK for the modular at least) , removing this beggining slash as the default value
