I have made an IONAPIExtDataSource IDO to retrieve data from an API and run it as a context app but I can't get it to work(I need it for another application that also has context information, not Infor M3).

I have added these two events on my form to communicate with the infor mingle application:
- StdFormPredisplay (Send Web Container Message Type) with these parameters: JSONMSGTYPE(registerMessageHandler) JSONPAYLOAD(inforBusinessContext) JSONMSGTOCHLD()
- StdWebContainerMessageRecieved (Form Script Method Type) with Descript() as a Parameter.



I have managed to get it to appear as a context application but it does not retrieve the context information to execute the API (It is just an example).


I have associated the variable that I inform in the script to the CUNO field to obtain the selected client in the Infor M3 program, but I get an error in each attempt and it never retrieves the information. What could I be doing wrong?
