Troubleshooting ​

Here are some common issues you might run into when using agency, and how to solve them.

Global install issue ​

If you get an error that looks like this:

node:internal/modules/package_json_reader:316
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'agency-lang' imported from /Users/foo/hello.js
    at Object.getPackageJSONURL (node:internal/modules/package_json_reader:316:9)
    at packageResolve (node:internal/modules/esm/resolve:768:81)
    at moduleResolve (node:internal/modules/esm/resolve:858:18)
    at defaultResolve (node:internal/modules/esm/resolve:990:11)
    at #cachedDefaultResolve (node:internal/modules/esm/loader:737:20)
    at ModuleLoader.resolve (node:internal/modules/esm/loader:714:38)
    at ModuleLoader.getModuleJobForImport (node:internal/modules/esm/loader:293:38)
    at #link (node:internal/modules/esm/module_job:208:49) {
  code: 'ERR_MODULE_NOT_FOUND'
}

You may have installed agency globally and tried to run an agent.

Two options:

Option 1: If you compiled and ran in separate steps like this:

agency compile foo.agency
node foo.js

Use the run command instead:

agency run foo.agency

Option 2: use pack to produce a standalone script:

agency pack foo.agency -o foo.mjs
./foo.mjs

Debugging your agent ​

Turn on logging. Create an agency.json with this content:

json
{
  "observability": true,
  "log": {
    "logFile": "logs.jsonl"
  }
}

Run your agent

agency run <filename>

Then view the logs

agency logs view logs.jsonl
