genfasm command failing in VPR flow

[muthu-iisc]

• genfasm command available in the VTR utilities is failing to generate a fasm file.
• Before this step I have successfully generated the place and route files for my design using the VPR tool.
• The fasm file is needed to generate the bit stream using BITMAN in the FABulous tool
• I have attached the screenshots of the above mentioned error with this query
• Could you please help me in resolving the issue?

Note:
genfasm is the utility used for generating the fasm file which will be required for bitstream generation.
I followed the steps mentioned in the VPR compilation page in the documentation.
