synchronous issues when using database operations when 'add' function is triggered

[niirdan]

Describe the bug
I am building a tool which receive files, and whenever there's an incoming file - i am calling db for crud operations. mongodb-atlas,
using mongoose.
looks like I can't force chokidar to wait until db operation finishes until serving the new incoming file (case when many files comes at once)
tried many configuration setting , non solved my issue
I am Sure that there's a solution but i can't understand how ..

Versions (please complete the following information):

• Chokidar version 3.5.3
• Node version v18.17.1
• OS version: windows 11

Steps to reproduce the behavior. Include filename and chokidar config.
ignoreInitial: true,
ignorePermissionErrors: true,
awaitWriteFinish: true,
binaryInterval: 10000
** I use the Unwatch() func to unlisten from a file by the end of each operation . **
Expected behavior
force chokidar to actually wait until db operations finishes and then serve the next file (when receive more than 2-3 files at once)
** Current Behavior**
duplications in db operations - code is running to fast and db cannot detect an existing entry on time.
