Hi all, We’re using the Twilio Module for SMS messaging. We’ve upgraded to Mx 9.4.0 but unfortunately, get a java error when compiling java to run. My knowledge lacks in this area and the Twilio Module has community support, does anyone have any advise on how to fix this, I will also reach out to the creator of the module and do some googling. Buildfile: C:\Users\gs\Documents\Mendix\What Matters Most Pilot-main\deployment\build_core.xml compile: [javac] Compiling 55 source files to C:\Users\gs\Documents\Mendix\What Matters Most Pilot-main\deployment\run\bin [javac] C:\Users\gs\Documents\Mendix\What Matters Most Pilot-main\javasource\twilioconnector\actions\SendSMS_JA.java:34: error: cannot find symbol [javac] Boolean sendSMS = Microflows.sendSMS(this.getContext(), SMSParamParameter1); [javac] ^ [javac] symbol: variable SMSParamParameter1 [javac] location: class SendSMS_JA [javac] Note: Some input files use or override a deprecated API. [javac] Note: Recompile with -Xlint:deprecation for details. [javac] 1 error BUILD FAILED C:\Users\gs\Documents\Mendix\What Matters Most Pilot-main\deployment\build_core.xml:29: Compile failed; see the compiler error output for details. Total time: 2 seconds UPDATE: And here begins the journey of learning java. This issue seems to be that the code was looking for “SMSParamParameter1” whereas the microflow had “SMSParam”. Updated the code and it compiled fine. Not sure why updating to Mx9 highlighted this, but i’ll give it a test and see if I broke anything!
