"duplicate key value violates unique constraint" error when using "Edit Feature in Place" with PostGIS Layer

[asgharibraheembaloch]

in our postgis database for line(road) layer we have defined primary key field and have applied unique not null constraint when i save split line segements manually by editing toolbar it works fine, but when i split lines with "split with lines" tool by turning on edit feature in place it gives me postgis error
"""
Could not commit changes to layer pk_roads

Errors: ERROR: 4 feature(s) not added.

Provider errors:
PostGIS error while adding features: ERROR: duplicate key value violates unique constraint "pk_roads"

but from my point of view it must have to work fine for "split with lines" tool if same splitting works from "Advance Digitizing Toolbar"

What is that fn_rd_partition? it's not part of QGIS nor postgis.

[asgharibraheembaloch]

data is partitioned in database and this function ensures whether user has not crossed the partition region

Hi,

Are you resolve your issue ?
I have tried the Lizmap 3.4.0pre and I get the same issue.
It does not split but cut instead of split.
May be something is missing.
