问题
When try to update status with link in linkedin api i'm getting this error frequently.
Example Link: http://www.world-grain.com/articles/news_home/World_Grain_News/2016/06/General_Mills_files_patent_on.aspx?ID={30B4213B-4E10-4AF6-9B56-0D5614D7AFD3}&cck=1
If i remove the { and } from the link it get posted. Even in linkedin site itself its not working.
Help me if anyone know the reason.

I was receiving the same error and the reason was that I didn't send values for all the keys in request's body. For example: "content" parameter in linkedin's request body is a dictionary with 4 keys:
- title
- description
- submitted-url
- submitted-image-url
I had no image url so I didn't set the key "submitted-image-url" at all. The solution was to set the value to empty string "".
I wonder why linkedin can't parse dictionary if it doesn't have all the keys but that's the way it works.
Hope this helps

You may need to URL encode the braces in your link:
http://www.world-grain.com/articles/news_home/World_Grain_News/2016/06/General_Mills_files_patent_on.aspx?ID%3D%7B30B4213B-4E10-4AF6-9B56-0D5614D7AFD3%7D&cck=1
I ran into the same error when I attempted to pass a URL with spaces. It published successfully after URL encoding the spaces (%20).
