This is really quite bad, I get the same error and the only change I made was used comfort update. Now LS version is
LimeSurvey Community Edition Version 6.3.6+231120
and my PHP has been 7.4 for a good few months and until this update was working well.
I played around with function from migliorati and came to conclusion that a lot of things work. But it seems that the response coming back from limesurvey might not be JSON? for example you do the usual limer options setup and then:
body.json = list(method = "get_session_key",
id = 1,
params = list(username = getOption('lime_username'),
password = getOption('lime_password')))
now you have the json rpc request (I think); then you give that request to httr::POST
POST(getOption('lime_api'),
content_type_json(),
body = jsonlite::toJSON(body.json,
auto_unbox = TRUE))
you get a response similar to :Response [
lime.server.yours/index.php/admin/remotecontrol
]
