Clicking Check and Save in Verilog Editor of Virtuoso returns error 'Extract Failed for Cellview"

I created a new Verilog cellview in the library I usually use in Virtuoso, and wrote the following code:

module digitalinverter (Vin,Vout);
    input wire Vin;
    output wire Vout;

    assign Vout=~Vin;

endmodule

However, when I go to click the "Build a database of instances, nets, and pins found in file," I get the following popup, as well as the pasted CIW output.

CIW Output:

ERROR (TIVLOG-43): The module 'digitalinverter' is not found in the source file inside the cellview 'FA24SP25Analog digitalinverter functional'.
Correct the module name in the source file or rename the cell to resolve the error.

The below is also what I have in my source file that I run before launching Virtuoso, in case that is relevant here:

#Cadence Virtuoso
module load cadence/cadence
module load cadence/innovus
#For parasitic extraction:
export ASSURAHOME=/opt/cadence/assura
export PATH=$ASSURAHOME/tools/bin:$PATH
export QRC_HOME=/opt/cadence/EXT152

export PATH=/opt/cadence/SPECTRE231/bin:$PATH
unset OA_HOME
#

# SKY130 Specific Pegasus

Thank you in advance!
