Description
Hello,
I am using amgx as a preconditioner with PETSc and when I try to use the MULTICOLOR_ILU solver, I get the following error message:
I believe I would have to change the config file itself to make this default as this is not currently a selected option in PETSc amgx. Would anyone know which files to modify and the necessary method to change these settings? My outlog and errlog are attached.

Research direction
Start by reviewing the MULTICOLOR_ILU configuration scope and the PETSc AMGX integration, using the attached outlog and errlog to reproduce the reported exception. Determine where reorder_cols_by_color and insert_diag_while_reordering are configured, then verify that the PETSc path applies the intended settings by rerunning the ILU test.
