Negative uin

I have run everything and I get:

I have tried to force the positive uin (272...) in the command line but it doesn't decrypt. Can you please look into this? Is this possible to have a negative uin?
According to this old article https://www.forensicfocus.com/articles/decrypt-wechat-enmicromsgdb-database/ negative UIN should be concated as string directly. i.e. you can try "-157". Does this work?
No. If I login to the website, my uin cookie is 272... But even if I force this number for UIN and I use my IMEI from my phone, I still can't decrypt the database. Am I doing something wrong?
Also if I subtract my two potential UIN (272...) and (-157...), I get 0xFFFFFFFF
I have WeChat version 7.0.17 and I don't think it can work. I have calculated the MD5 as explained in the referenced article.
