Hello Knime Support! I still have troubles with the JSON Reader introduced in KNIME 4.4 My original Post was automatic closed but can be found here: [image] new JSON Reader in KNIME 4.4 KNIME Extensions Hello Community! I read a json output from an internal http Adress. For the Request I must specify some parameters like http://…index.php?key=XYZ&format=json With the new JSON Reader I get an error, that the specific file ‘…/index.php’ does not exists. Calling index.php without the parameter will result in a http error 500 internal server error. The JSON Reader Node does not execute and shows the error "Execute failed. The specified file /…index.php does not exists. I asume this error is beca… I now have found what maybe leads to the Problem: My URL is 333 chars long (and will grow over time), since one parameter is a comma seperated list of numbers. If I truncated the list to below 300 chars everything works fine. Could you please recheck this issue Thanks Matthias

Hi, I think the problem is not the URL length, but a timeout. Maybe the longer your URL, the more data you fetch and the longer it takes the server to respond? I just tried the JSON Reader with this URL: https://httpbin.org/anything?long=abcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxzabcdefghijklmnopqursuvwxz Which just returns information about the request as JSON back to the caller. When I did not increase the timeout, I got the same error as you. When I adjusted it to 20 seconds, the node ran through fine. But generally, it may be better to use the GET Request for such cases, because it can handle HTTP error codes much more smartly. If the server sets the content-type header to application/json, the node will automatically return a JSON cell. Kind regards, Alexander [Screenshot 2023-06-20 at 10.11.00]
