Nagvis Error in Sidebar

Hi,

I have an error when displaying Nagvis to the sidebar. It is a quite long error message:

Failed to parse JSON request: 'Error (Error): Class "PDO" not foundarray(1) { [0]=> array(2) { ["function"]=> string(15) "nagvisException" ["args"]=> array(1) { [0]=> object(Error)#14 (7) { ["message":protected]=> string(21) "Class "PDO" not found" ["string":"Error":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(86) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/classes/CorePDOHandler.php" ["line":protected]=> int(279) ["trace":"Error":private]=> array(4) { [0]=> array(5) { ["file"]=> string(86) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/classes/CoreAuthModPDO.php" ["line"]=> int(57) ["function"]=> string(4) "open" ["class"]=> string(14) "CorePDOHandler" ["type"]=> string(2) "->" } [1]=> array(5) { ["file"]=> string(87) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/classes/CoreAuthHandler.php" ["line"]=> int(47) ["function"]=> string(11) "__construct" ["class"]=> string(14) "CoreAuthModPDO" ["type"]=> string(2) "->" } [2]=> array(5) { ["file"]=> string(79) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/functions/index.php" ["line"]=> int(44) ["function"]=> string(11) "__construct" ["class"]=> string(15) "CoreAuthHandler" ["type"]=> string(2) "->" } [3]=> array(4) { ["file"]=> string(76) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/ajax_handler.php" ["line"]=> int(59) ["args"]=> array(1) { [0]=> string(79) "/opt/omd/versions/2.2.0.cre/share/nagvis/htdocs/server/core/functions/index.php" } ["function"]=> string(7) "require" } } ["previous":"Error":private]=> NULL } } } } ': Expecting value: line 1 column 1 (char 0)

Does anyone have this error too? Or knows how to solve it?
Thanks in advance

I don’t have this error. But I am running NagVis in CheckMK 2.1 Raw. Looks like you are in 2.2 Raw. Perhaps worth to mention what build you are on and what you did to get this error, maybe you encountered a bug in the code.

Assumptions based on the error, something about a PHP Data Object being NULL and something to do with authentication.
