LT on MAC Missing 'text' parameter error

Hi,
I would like to have LanguageTool on my mac running as server and later used in TexStudio.
I’ve installed Java 9.x and LanguageTool 3.2.
When I launch LanguageTool server through LanguageTool GUI and open

http://localhost:8081/v2/check?language=en&text=my+text

in the internet browser i got following:
This XML file does not appear to have any style information associated with it. The document tree is shown below.



However for http://localhost:8081/ in browser I got:
Error: java.lang.IllegalArgumentException: Missing ‘text’ parameter

Is this proper response? I guess not. Any clue what could I do? Thanks

P.S: The firewall is switched off.

LanguageTool 3.2 doesn’t offer the new API (with v2 in the path). For http://localhost:8081/ you get the expected response, as there was no text parameter. http://localhost:8081/?language=en-US&text=my+texd should work.

yes, this works. thanks.

First thing solved. The second thing is connecting to TexStudio. When I run TS and write simple “this is a example” no underlining is visible. Any clue?
