About Honeybee's Error "Environment variable name or value too long"

Hi, everyone.

When I run an optimization calculation using HoneybeePlus, after the calculation has run to some extent (About 1200 times), I get the error “Environment variable name or value too long” and the calculation stops.

I found a similar problem and discussion with Butterfly in the previous topic (URL below), does Honeybee Plus still have this error?

And if this error still remains, how can I fix it?
Please let me know.

Thank you

Hi @Toshihide, can you provide more details? What component gives you the error? Can you provide an screenshot?

Hi @mostapha, thank you for your reply.

I attach screenshot of my grasshopper file and error message.
This error was reported by the HoneybeePlus_Run Radiance Analysis component.
How can I solve this?
