deno run on a built bids-validator.js: Attempted to load JSON module without specifying "type"

[yarikoptic]

Trying to run out of deno-build branch using wrapper proposed in

• Create shim to run deno bids-validator #1942

but getting

+ bids-validator 7t_trt --ignoreNiftiHeaders
TypeError: Attempted to load JSON module without specifying "type": "json" attribute in the import statement.

that is with

❯ bids-validator -V
v1.14.6-dev.0-9-gdc61d0f3.deno

❯ cat `which bids-validator`
#!/usr/bin/env bash

deno run --allow-read --allow-write --allow-env --allow-net --allow-run "$(dirname "$0")"/bids-validator.js "$@"

so there is --allow-net if that is of importance.

So it seems to do use some internal copy of schema but not clear why it fails to get/use that one from a URL if it wants so (should it download it every time? sounds a bit too much)

Here's the relevant code:

bids-validator/bids-validator/src/setup/loadSchema.ts

Lines 21 to 23 in dc61d0f

	const schemaModule = await import(/* @vite-ignore */ schemaUrl, {
	assert: { type: 'json' },
	})

This is an issue with how the module is transpiled, it might be configuration or a bug in esbuild or the Deno module plugin.

bids-validator/bids-validator/build.ts

Line 9 in dc61d0f

import { denoPlugins } from "jsr:@luca/[email protected]"

Imports are always cached in deno. You can refresh the cache with deno run --reload .... The idea here is to load both ways, as a static import that can be bundled and a dynamic import that can be modified at runtime by the tool.

FWIW, adding --reload didn't help

❯ deno run --reload --allow-read --allow-write --allow-env --allow-net --allow-run /tmp/bids-validator/bids-validator.js 7t_trt --ignoreNiftiHeaders
