Import Health Rule error message - Unexpected character (- (code 45)) in numeric value

Hi everyone,

Has anyone faced the following problem when importing a health rule in JSON format?

I'm using the following curl command:

curl -sL -w "%{http_code}" -X POST --user "${USER}:${PASS}" \
-H "Content-Type: application/json" -F file=@${FILE}.json \

which in every JSON file I tried, returns me this error:

"statusCode" : 400,
"message" : "Unexpected character (- (code 45)) in numeric value: expected digit (0-9) to follow minus sign, for valid numeric value "

... even if I'm using the same JSON as in the official documentation:

The JSON files I've tried do not contain any hyphen characters, so apparently the request payload is not related to the error cause.

Anyone been there?

Thanks and regards.



Hi there


Can you share your health rule json file you are trying to import?


Did you build it from scratch, or did you export it, and you are trying to import it again?


The query you should be using is as follows


Need to use --data, not -F File


curl -X POST --user user@user:password "https://<controller details/controller/alerting/rest/v1/applications/<application ID>/health-rules" -H "Content-Type: application/json" --data "@test2.json"

Good morning Mario,

Thanks for your tip, once I changed to --data instead of -F file, it worked!!!
