The question is published on by Tutorial Guruji team.
I’ve been trying to send a message from a web page using JavaScript to a Unity function but I continue to get a value not found when calling the function. The object associated is a child object of the canvas so Im not sure that’s an issue or not. Ive tried a combination of things to make it
coilScore is a float and I’m simply passing the number across.
My attempts to reach child object.
gameInstance.SendMessage('CoilValue', 'ReceiveCoilScore', coilScore);[![enter image description here][1]][1]
gameInstance.SendMessage('InGameCanvas/CoilValue', 'ReceiveCoilScore', coilScore);
gameInstance.SendMessage('InGameCanvas', 'ReceiveCoilScore', coilScore);
gameInstance.SendMessage('InGameCanvas.CoilValue', 'ReceiveCoilScore', coilScore);
Error:
SendMessage: object InGameCanvas/CoilValue not found! a4527c6b-a81a-4c23-8861-f3553ac675c8:8:48803
Type: number Total coilScore: 0.000001401 meta_monetization_handler.js:34:10
EDIT
Ive added additional information below this line for clarity.
The index.html is calling a .js file. Inside that .js file I am parsing multiple parameters but the one item I am trying to do is send a message from the .js file to Unity.

Answer
I changed the canvas to match the camera view. I also noticed much later that javascript was using toPrecision(4) and I had a function that wa taking a float. toPrecision was conerting the float to a string and string to use that as an argument hence it failed.
Solution : Ensure that what I have been sending was a string and the function on the receiving end takes a string.
public void ReceiveCoilScore(float newValue)
{
//gameSession.coilScore = newValue;
//coilScoreText.text = string.Format("{0:N9}", gameSession.GetCoilScore());
coilScore = newValue;
coilScoreText.text = string.Format("{0:N9}", coilScore);
}
Converting float to string
coilScore = this.runningTotal.toPrecision(4);
console.log("Type: " + typeof coilScore + " Total coilScore: " + coilScore );
gameInstance.SendMessage('CoilValueTextObject', 'ReceiveCoilScore', coilScore);
