Thanks for the design. I see the following CW in xdc:
Warning on LVDS25 is self-explanatory. I would suggest using the IO planner GUI to assign PACKAGE_PIN and IOSTANDARD value. The correct IOSTANDARD value is LVDS_25
The CW on set_property is due to incorrect object specified for get_nets commands.
There is no net with name "clk_out_IBUFDS" in your design. You can check this by opening synthesized / implemented design and run "get_nets *" which will list all the nets present in your design.

Hi @pallavi52 ,
In addition to @syedz suggestions, In the shared test3.xpr project, I see that you have specified the IO constraints in the TCL script (script.tcl) that gets used during bitstream generation as you have set the script.tcl file to the tcl.pre of bitstream settings.
Ideally, we should not use the IO constraints after routing the design as it requires the placement of the design again.
The main reason you are seeing the error is due to the set_property constraint present in the script.tcl file. You are specifying the IO constraints on SYS_RST port which is not present in your design. You need to comment on the LOC and IOSTANDARD constraints present in the script.tcl file to overcome the error during bitstream generation.
Also, I see that there is no logic in your shared design and has only one IBUFDS and one OBUF.
