Currently, calling the connections api with the public-profile-url is causing an internal server error

Question

Currently (but not usually), if you call the following url you get an internal server error: https://api.linkedin.com/v1/people/~/connections:(id,headline,picture-url,summary,first-name,last-name,formatted-name,location:(name),industry,positions,num-connections,num-connections-capped,api-standard-profile-request:(url,headers),public-profile-url)?format=json

Remove the public-profile-url and call the following url, it works: https://api.linkedin.com/v1/people/~/connections:(id,headline,picture-url,summary,first-name,last-name,formatted-name,location:(name),industry,positions,num-connections,num-connections-capped,api-standard-profile-request:(url,headers))?format=json

Why?

Answer 1

They seemed to have reduced the number of contacts you can get each time you request them. I used to ask for 500 and it worked for a long time, and then last week it stopped working and instead would return:

 <status>500</status>
 <timestamp>1424451457253</timestamp>
 <request-id>HISKBDLSOA</request-id>
 <error-code>0</error-code>
 <message>Internal service error</message>

Now, I request 250 contacts each time and it works again.
