Error 500 with JSON in Find operation

[NiklasRingdahl]

Hi.

I am using the Find operation to query one of my layers, and it works in the html form view, returning the expected features. But when I switch to output format Json "&f=json", I get:

{"error":{"code":500,"message":"Object reference not set to an instance of an object.","details":[]}}

Url that returns correct data (in html):
http://<myservername>/ArcGIS/rest/services/<myservicename>/MapServer/find?searchText=Kulla&searchFields=SITE%2CFULLNAME&layers=0

Url that returns the error data (in json):
http://<myservername>/ArcGIS/rest/services/<myservicename>/MapServer/find?searchText=Kulla&searchFields=SITE%2CFULLNAME&layers=0&f=json

Any ideas?

Best regards,
- Niklas

I know its been awhile since you posted this but I ran into a similar situation when the rows being returned contain special characters like ' " / \ etc. Not sure which version you are using but after we installed the latest update or service pack our problem was fixed.

Thanks! I'll look into that. What version or patch did you upgrade to?

I just checked and our servers are all running 9.3.1. I have yet to install 9.3.1 SP1 or SP2 so I think it was the jump from 9.3. to 9.3.1 that did it. I also remember having to update our exported Web Service Handlers because our exposed web server is a Linux OS running Apache/Tomcat but our AGS 9.3.1 for the Java Platform is internal to the firewall running a Windows OS.
