Centeur emacs org preview show internal error

[ZhengshuaiPENG]

Hi seagle0218,

I am using centaur emacs now and I want to preview my org file. But when I use M-x grip-mode, the web page shows me 500

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

And I saw there was a md file generated.

I already installed python3 and grip in my system (OSX), is there any way to debug it?

And here are outputs in the message buffer

Saving file /Users/zhengshuai.peng/Workspace/notes/ProductResearch/Hologres/hologres_summary.md...

In addition, I saw the command in emacs like

grip version: 4.5.2 It seems that - Grip is not supported in grip command

The command is incorrect. user and password are not set. I have no idea why they are nil.

;; A GitHub username for API authentication
(setq grip-github-user "")

;; A GitHub password or auth token for API auth
(setq grip-github-password "")

Thanks for your reply I added these configurations in custom.el in my centaur config I also tried to upgrade all centaur configuration and packages to lastest yesterday. The only changed file is custom.el is there any idea?

[seagle0128]

1. M-x list-process
2. Open grip process buffer like *grip-xxxx*.
3. Check the logs.

Hi seagle0128,

I checked the process log Seems that it's an authorization issue.

So the problem is my configuration is not correct? it doesn't take effect when set them in custom.el

[ZhengshuaiPENG]

I also tried use (setq-default grip-github-user "xxx") and (setq-default grip-github-password "xxx"). No luck with this way.

Tried another way, use customize-group, I saw the grip-github-user is nil, tried to edit it, but I can't apply and save

Rootcause Found In .emacs.d/lisp/init-markdown.el

If I changed grip-github-user and grip-github-password here, the preview works.

I don't understand that in this code snipper

(setq grip-github-user (car credential)
     grip-github-password (cadr credential)

how (car credential) to get the user name and the password

[seagle0128]

Please update Centaur Emacs.

Hi, @seagle0128

Thanks for your update.

I create a ~/.authinfo and put login {user_name} password {token}, the grip mode works.

But I found that if I just set the (setq grip-github-user "{user_name}) and (setq grip-github-password "{token}") in my custom.el by following the README, the grip mode still doesn't work.

Is there a way that make grip mode work when I set these in my custome.el?

[seagle0128]

I believe it works.
