Re-building base overlay PYNQ 2.5.4

I am using PYNQ-Z2 Board
PYNQ Image V2.5.4 since I have Vivado 2019.2

I am trying to rebuild the base overlay
but I keep running into this error:
Skipping building color_convert
Checking color_convert
can’t unset “period”: no such variable

everytime I put in the tcl command line source ./build_base_ip.tcl

Any idea on how to fix this ?
