Mautic REST API - "false" overwriteWithBlank attribute in PUT request overwrites with blank anyway

Your software
My Mautic version is: 3.2.5
My PHP version is: PHP Version 7.3.24-3+0~20201103.72+debian9~1.gbp945915
My Database type and version is: MariaDB 10.5.8

What I expected
HTTP request PUT (/contacts/ID/edit) should not overwrite empty fields with blank when overwriteWithBlank is set to false
(cf. Mautic Developer Documentation ==> overwriteWithBlank: If true, then empty values are set to fields. Otherwise empty values are skipped)

Language used : NodeJS + Axios module for HTTP requests

My problem
HTTP request PUT (/contacts/ID/edit) request that overwrites all empty contact fields to blank, regardless the attribute overwriteWithBlank set to false.

Steps I have tried to fix the problem
I tried overwriteWithBlank set to true as well, I get the same result. empty fields set to blank.

Can I get some guidance to use the overwriteWithBlank property in the appropriate way?

I see that it is covered on GitHub.

Just got to be patient. :slight_smile:
