Runtime Error: "src.js is not in the SourceMap" #1045
Description
The Runtime has started throwing this weird error: R/T Error: "src.js" is not in the SourceMap.
As in:
R/T Executing expression (1 operations)
R/T Starting operation 1
R/T Add data elements to state aborted with error (4.109s)
R/T Cleaning up state. Removing keys: configuration
R/T Run complete with status: crash
R/T Error: "src.js" is not in the SourceMap.
Repro
Run this step with an empty dataclip:
fn(state => {
state.dataElements.map(x => x);
return state
})
state.dataElements.map() will throw a JS error. While processing that error, the Runtime will crash.
Expected Behaviour
Users should see something like this:
[R/T] ✘ TypeError: Cannot read properties of undefined (reading 'map')
at vm:module(0):2:22
@openfn/language-common_3.1.0/dist/index.cjs:534:12
[R/T] ✘ Error occurred at: job-1
[R/T] ✘ 2: state.dataElements.map((x) => x);
[R/T] ✘
In CLI it seems to work fine

Weirdly this seems to work just fine in the CLI - implying that the actual issue belongs to the engine or runtime

This must have been around since the sourcemapping feature came out 🙀 It's all to do with how the worker pulls the sourcemapped file out of the filemap.
