What happened?

Hello, I have a question about the --extra-headers parameter.
I tried to use lighthouse https://huixie.iflyrec.com/list --extra-headers "{"sessionkey":"32a86fbaac004c048b0ab674875c1657","websessionkey ":"c063d532ca5a4d50a0a97f5e944339bd"}"
I used it to test the performance of my product, but the cookie information was not set successfully, is there something wrong with the way I wrote it?

Can you help me see what my problem is? A million thanks.

What did you expect?

Please help me find my problem.

What have you tried?

I also tried to use, read the local json file, but also did not succeed, the json content is: {"Cookie": "sessionkey=6032da97e3c44fcb89ab9ca7effe1003&domain=huixie.iflyrec.com; websessionkey= 77d975e1e89047d2bfafb75c316a181a&domain=.iflyrec.com"}
