Using assert in pinescript

Question

I would like to use assert in pinescript for bug detection. assert statement is available in python and C/C++. I hope there is an easy way to use assert in pinescript.

There's a library available but it looks complicated to me.

There is no assert in pinescript.

The library you linked is actually pretty good.

Alternatively, there is runtime.error which you can use conditionally.

When called, causes a runtime error with the error message specified in the message argument.

Something like this:

if barstate.islast and ta.cum(volume) == 0
    runtime.error("No volume is provided by the data vendor.")
