==================
Hi guys.
We updated limesurvey from 3 to 5.3, and now API seem not working: when I try (I'm working in R with limer package) a
get_session_key()
now I obtain an error:
Error: Argument 'txt' must be a JSON string, URL or file.
Everything was running before the update.
Please, someone can help me?

Here is the post mentioned above , but its solution seems mainly related to the R limer package.

I am experiencing a similar issue, where get_session_key results to 500 Internal Server Error:

PHP Fatal error:  Uncaught Exception:
Unable to connect to .../admin/remotecontrol in /var/www/.../application/libraries/jsonRPCClient.php:146
Stack trace:
#0 /var/www/.../requests/export_responses.php(17): jsonRPCClient->__call()
#1 {main}
thrown in /var/www/.../application/libraries/jsonRPCClient.php on line 146,
referer: https://.../index.php/786859

While this works perfectly with LimeSurvey Version 5.3.24+220711 on localhost, it won't work on our production-site (using the exact same version).

(Note: The url, user and pass above are edited for privacy reasons)

Since ...

• the API-related settings and request-URL are correct (as described in this previous post )
• the username and password belong to a normal registered user
• the login uses the auth_db (internal database authentication) method

... what else might be wrong?

Thx in advance !


 

For us this works:

library(limer) 
options(lime_api = ' yourdomain.nl/index.php/admin/remotecontrol ')

options(lime_username = 'report')
options(lime_password = 'password')
session_key <- get_session_key()

Thanks. So, probably the answer is that remotecontrol works after the 5.3 update.

To rephrase my question above , could someone point me to the configuration(s), which cause the API to return a 500 Internal Server Error?
(while using the same code & LimeSurvey settings and version, it works locally - using a XAMPP server)

Thx!

Sorry, cannot help you here, we never used your way of working.
