<p>In these situations you might be able to use <code>try/catch</code> with a <code>console.log</code> of the catch error argument to reveal the underlying error message.</p>
<p>For example, this code without a <code>try/catch</code> will log errors without the message <code>This is the error text</code>:</p>

<p>Azle compiles and bundles your TypeScript/JavaScript into a final JavaScript file to be included and executed inside of your canister. Inspecting this final JavaScript code may help you to debug your application.</p>
<p>When you see something like <code>(azle_main:110643)</code> in your error stack traces, it is a reference to the final compiled and bundled JavaScript file that is actually deployed with and executed by the canister. The right-hand side of <code>azle_main</code> e.g. <code>:110643</code> is the line number in that file.</p>
