Error while running the CodeChecker analysis on linux kernel modules.

I am trying to run the CodeChecker analysis on test linux kernel module. I get the following output.

Building the module:

(venv) [sahil@HP_242 ~]$ CodeChecker log -b "cd ~/test_kernel_module && make clean && make -j4" -o ~/test_kernel_module_compilation.json
