One of my questions that I'm trying to solve is about the error message "Cannot read properties of null (reading 'transition'). What does it mean?". I tried using the solution suggested in this question on integration of 'mychart.update()': https://github.com/chartjs/Chart.js/issues/5149. However, I encountered another error when I tried to implement it.
TypeError: Cannot read properties of null (reading 'length')

Below is the last code I attempted to run:
<template>
<div> Profit/Attendance <div class="small">
<canvas id="mychart" height="400"></canvas>
</div>
</div>
</template>
...
And also, I tried this alternative option:
<template>
<div> Profit/Attendance <div class="small">
<canvas id="mychart" height="400"></canvas>
</div>
</div>
</template>
...
When I examined the string in the debugger, I found references to specific lines of code. The last reference pointed to this line:

Further investigation led me to this line of code:
