Got TypeError when try to run a simple [chat] block

[WaysonWei]

Hi, I am running Dust locally, when trying to run a simple app, got this error:

Error inmessages_code: TypeError: Error parsing args at position 0: serde_v8 error: invalid type; expected: object, got: string at code_block.js:9:19 at code_block.js:10:6

Here is the screenshot:

Not sure it is a bug or I did something wrong.

Hi hi! We don't officially support local deployment of Dust. But no problem with you attempting it of course.

This looks like an error coming from the core service. Anything more useful in the logs?

[WaysonWei]

Hi, @spolu. Thank you for getting back to me.

Yes, I think something to do with the javascript we passed into deno core, I didn't change any line of that, but I did print json_args and js_code from core/src/deno/script.rs as follow:

But these seem to be fine, json_args shouldn't be a problem here, not sure where goes wrong. I ran core with this command in my terminal: cargo run --release --bin dust-api

[spolu]

mmmh the command looks fine and the error is surprising indeed. What version of Rust are you using?

[WaysonWei]

I am running this version in mac m1: rustc 1.78.0 (9b00956e5 2024-04-29)

[spolu]

We're building with 1.76 even if I don't expect this to be the issue. Just out of curiosity.

[WaysonWei]

Seem to be a problem of rust version, but not 100% sure, use rust 1.76 to build the docker image then working fine. Thanks.
