When I publish a service, appears an error that says: "Loops are not allowed: Loop 1: ......" But I don't have any loop in my app. I know what is a loop, and the app has none. It's an big app, with more than 125 processors, maybe 200 processors will be necessary. Do services have a processor o connections (arrows between processors) limit? How can I "debug" to found the errors on the service?</P><P>Thank you very much for any idea.</P></BODY></HTML> Mon, 10 Aug 2020 15:05:23 GMT https://community.esri.com/t5/arcgis-geoevent-server-questions/loop-errors-in-geoevent/m-p/322700#M1345 Jose_RamonVencelles_Garcia 2020-08-10T15:05:23Z Re: Loop Errors in GeoEvent https://community.esri.com/t5/arcgis-geoevent-server-questions/loop-errors-in-geoevent/m-p/322701#M1346 <HTML><HEAD></HEAD><BODY><DIV style="font-family: sans-serif; color: #3d3d3d; font-size: 11.5pt;"><P style="margin: 8.0pt 0in 8.0pt 0in;"></P><P>Hello <A href="https://community.esri.com/migrated-users/404495">Jose</A> –</P><P style="margin: 8.0pt 0in 8.0pt 0in;">To be clear, you are developing a custom web application which complements or reproduces what you can do using the GeoEvent Manager?&nbsp; So you're authenticating with the GeoEvent Server's administrative REST API to (probably automate) the creation of a bunch of processors, publishing a workflow connecting these processors as a GeoEvent Service.</P><P style="margin: 8.0pt 0in 8.0pt 0in;">Does the service publish, albeit in an error state?&nbsp; If the service publishes you can export an XML representation of the configuration and inspect that to look for where the GeoEvent Service publication and validation is detecting a loop.
