Compiling web-tree-sitter using ASSERTIONS=1, via script/build-wasm --debug, refines the error message to:
Aborted(Assertion failed: undefined symbol `_ZTVN10__cxxabiv117__class_type_infoE`.
perhaps a side module was not linked in?
if this global was expected to arrive from a system library,
try to build the MAIN_MODULE with EMCC_FORCE_STDLIBS=1 in the environment)
Compiling with EMCC_FORCE_STDLIBS=1 does not make a difference.

The issue is that web-tree-sitter performs dead code elimination, and eliminates all but a select few functions listed in exports.json. The following patch to tree-sitter ensures that the functions used by tree-sitter-haskell are kept:

With the above patch applied to tree-sitter running a simple parser test results in the following error:
TypeError: Cannot read properties of undefined (reading 'apply')

To help reproducing these errors, here is a simple script which uses the generated wasm, to be called as script/parse-example.js:
#!/usr/bin/env node
const fs = require('fs')
const Parser = require('web-tree-sitter');
if (process.argv.length < 3) {
console.log('Usage: script/parse-example.js <haskell-file>')
process.exit(1)
}
const fileName = process.argv[2]
const sourceCode = fs.readFileSync(fileName, 'utf8')
Parser.init().then(() => {
Parser.Language.load('tree-sitter-haskell.wasm').then((Haskell) => {
const parser = new Parser;
parser.setLanguage(Haskell);
const tree = parser.parse(sourceCode);
console.log(tree.rootNode.toString());
});
});from tree-sitter-haskell.

Created two issues which may help debug such problems in the future (tree-sitter/tree-sitter#1565 and tree-sitter/tree-sitter#1566).
