hmmm.. maybe the rquickjs runtime doesn't have whatever inner method we're wrapping in JS in the test library.

[mhmd-azeez]

yeah, the host function in xtp plugin test never gets called, so the glue code breaks down somewhere

[nilslice]

It's odd - I don't see anything calling any JS builtin functions that would imply the runtime is missing something:

I think @bhelx had some idea what might be going wrong

Ok, the stack says the as_big_int() call fails us

js-pdk/crates/core/src/globals.rs

Lines 482 to 486 in 05cecf2

	let ptr2 = args
	.get(2)
	.unwrap()
	.as_big_int()
	.unwrap()

Nice! how did you get the stack? even setting RUST_BACKTRACE didn't give me anything useful!

It's in your initial pasted output 😆 - sorry, not the wasm stack, just Rust's when the code panics

I have been staring at this error almost all day, and didn't see that crates/core/src/globals.rs:486:26: line 🤦

[nilslice]

Been there, done that! It happens 🙇
