Hi all.

Can I exclude an exception from a node.js request as an error?

The information I have is:

request name:

_/api/data/v1/staging/fact/periodical_

file that throws the error:

_/stmonit/share/micajero360/back-end/node\_modules/express/lib/express.js_

and the error message:

_“(Staging) You are duplicating ENTRY. Error”_

Can somebody help me?

thank you in advance

Try go to specific nodejs service, edit, then go to error detection, turn on override global error detection settings. then enter your error string into new exception added in “Ignore exceptions” part.

Ok, now i see your issue. Have you tried to enter any string (or your string) into class input box and then your string into 2nd input box ?
