Javascript code to generate OTP code based on secrets is not working

[dougleenhouts]

I have checked the following:

• [X] I use the newest version of bruno.
• [X] I've searched existing issues and found nothing related to my issue.

Describe the bug

I use this well-known script in Postman to generate a 6-digit OTP code in a pre-request script based on a variable for a secret key: https://gist.github.com/ptrstpp950/42660823675f6bf2f2d2f1503663553a

But when I try to run the same pre-request script in Bruno I get this error:

Error invoking remote method 'send-http-request': TypeError: Cannot read properties of undefined (reading 'length')

I don't see any equivalent to the Postman console to find any more details either.

Hi @dougleenhouts, I tried to run the script on our latest version(1.34.2) and it worked fine. I've attached the bruno collection here for you to try it out. Create an environment after you import it. Please let me know how it goes! Temp Test.json

Thanks @sreelakshmi-bruno , that attached collection works in safe mode, but in developer mode (on 1.34.0) it returns:

Error invoking remote method 'send-http-request': TypeError: X.jsSHA is not a constructor

Hey @dougleenhouts,

In Bruno, we use two different runtimes for Safe and Dev modes: a browser-based runtime and a Node-based runtime. In the script above (line 2246), there is no need to export the module in the Node runtime code. If we fix that, it won’t be an issue. In the updated gist, we have removed the export logic.

PS: To understand the diff between the behavior try running the script in Node.js runtime and in browser

Hi @dougleenhouts, I've attached the collection we've created by removing that function. Please check it out and let us know how it goes.
