Description:

Script item parameters are wrongly escaped if set via user macro.

Steps to reproduce:

Create host and script item with parameter "urls" with value '["https://www.srv1.com","https://www.srv2.com"]'. The javascript vill be simply:

return value;

This approach returs in item latest data correct expected value:

{"urls":"[\"https://www.srv1.com\",\"https://www.srv2.com\"]"}

Now define on the host user macro {$URLS} with the same parameter value and use this macro for item parameter value.

Now the item last value will be:

{"urls":"[\\\"https://www.srv1.com\\\",\\\"https://www.srv2.com\\\"]"}

There are added additional backslashes for each doublequote in parameter value.

Expected:
The value returned for the script item will be correctly escaped if user macro is used for item parameter.

Maybe this problem have something in common with existimg issue ZBX-24970
