Hello, I created a code for solving the finite element method using the PCBDDC method according to ex71, but I got the following error at the end, I can't find out the cause of the error, can you tell me what the error is based on the error message? (PS. I have tried: Mat AA. PetscCall(MatConvert(A, MATAIJ, MAT_INITIAL_MATRIX, &AA)). to change the matrix type and then solve for AA, it works fine)
