NO_ABIS_FOUND

NO_ABIS_FOUND

Error message

no ABI found at '${inputs}'

What it means

After runTypegen resolves inputs to filepaths and reads each into abiFiles, it asserts that at least one ABI file was loaded. A zero-length result means the supplied globs/paths matched nothing on disk (the filepaths array was empty after glob expansion).

Solutions

1. Confirm the glob pattern matches files from the configured cwd (test with a glob library first).
2. Use absolute or repo-relative paths and verify the files exist before invoking typegen.
3. Ensure CI copies/generates ABI files before the typegen step.

Example fix

// before
runTypegen({ input: ['abis/*.json'], cwd: '/wrong/dir', ... });

// after
import { globSync } from 'glob';
const cwd = process.cwd();
const hits = globSync('abis/*-abi.json', { cwd });
if (!hits.length) throw new Error('no ABIs matched');
runTypegen({ input: ['abis/*-abi.json'], cwd, ... });

import { globSync } from 'glob';
function assertGlobHits(patterns: string[], cwd: string) {
  const hits = patterns.flatMap(p => globSync(p, { cwd }));
  if (!hits.length) throw new Error(`no ABI files matched ${patterns.join(', ')} in ${cwd}`);
}

When it happens

Trigger: Supplying an `input` glob that resolves to no files (wrong cwd, wrong pattern); pointing at a directory containing no `-abi.json` files; glob syntax error that silently matches nothing.

Common situations: Running typegen from the wrong working directory; glob pattern with a typo (`abis/*.json` vs `abis/**/*-abi.json`); CI checkout missing the ABI artifacts step.
