Temboo call hangs Arduino - parse-platform

Question

I am using an Arduino Uno with the Desloo W5100 Ethernet shield. Whenever I try to make calls to Parse using Temboo, the device just hangs. Sometimes for minutes...sometimes indefinitely. Here is what I run:
void updateParseDoorState() {
if (!ENABLE_DOOR_STATE_PUSHES) {
Serial.println("Door state pushing disabled. Skipping.");
return;
}
Serial.println("Pushing door state to database...");
TembooChoreo UpdateObjectChoreo(client);
// Invoke the Temboo client
UpdateObjectChoreo.begin();
// Set Temboo account credentials
UpdateObjectChoreo.setAccountName(TEMBOO_ACCOUNT);
UpdateObjectChoreo.setAppKeyName(TEMBOO_APP_KEY_NAME);
UpdateObjectChoreo.setAppKey(TEMBOO_APP_KEY);
// Set profile to use for execution
UpdateObjectChoreo.setProfile("ParseAccount");
// Set Choreo inputs
String ObjectIDValue = "xxxxxxxxxx";
UpdateObjectChoreo.addInput("ObjectID", ObjectIDValue);
String ClassNameValue = "DoorState";
UpdateObjectChoreo.addInput("ClassName", ClassNameValue);
String ObjectContentsValue = (currentState == OPEN) ? "{\"isOpen\":true}" : "{\"isOpen\":false}";
UpdateObjectChoreo.addInput("ObjectContents", ObjectContentsValue);
// Identify the Choreo to run
UpdateObjectChoreo.setChoreo("/Library/Parse/Objects/UpdateObject");
// Run the Choreo; when results are available, print them to serial
int returnStatus = UpdateObjectChoreo.run();
if (returnStatus != 0){
setEthernetIndicator(EthernetStatus::SERVICES_DISCONNECTED);
Serial.print("Temboo error: "); Serial.println(returnStatus);
// read the name of the next output item
String returnResultName = UpdateObjectChoreo.readStringUntil('\x1F');
returnResultName.trim(); // use “trim” to get rid of newlines
Serial.print("Return result name: "); Serial.println(returnResultName);
// read the value of the next output item
String returnResultData = UpdateObjectChoreo.readStringUntil('\x1E');
returnResultData.trim(); // use “trim” to get rid of newlines
Serial.print("Return result data: "); Serial.println(returnResultData);
}
/*while(UpdateObjectChoreo.available()) {
char c = UpdateObjectChoreo.read();
Serial.print(c);
}*/
UpdateObjectChoreo.close();
Serial.println("Pushed door state to database!");
Serial.println("Waiting 30s to avoid overloading Temboo...");
delay(30000);
}
I get this in the serial monitor:
Current state:6666ÿ &‰ SP S P U WR SR R PR P 66Temboo error: 223
This indicates that there is some type of HTTP error, but I never get to print what the error is...because the serial monitor is stuck there forever. And eventually disconnects.

I work at Temboo.
It sounds like you might be running out of memory on your board (a common occurrence on resource-constrained hardware like Arduino). You can find our tutorial on how to conserve memory usage while using Temboo here:
