There is an error while building the frontend.

[SharglutDev]

To fix your build issue, you need to modify in :

• AddOrEditStudyModal l.408 : value={currentStudy.budget ? currentStudy.budget : ''}
• AddOrEditProjectModal l.387 : value={currentProject.budget ? currentProject.budget : ''}

and fix the comment below and it should be ok :)
