Error message
Expected input and output file paths
What it means
wrap-find-elements-as-global.js mirrors wrap-as-global.js but for the findElements TypeScript atom, exposing it as window.bot.locators.typescript.findElements. It requires two positional CLI args [inputPath, outputPath] and throws before file I/O if either is absent. Build-time helper invoked by Bazel, not user-facing.

Solutions
- Invoke as: node wrap-find-elements-as-global.js <compiled-input.js> <wrapped-output.js>.
- Verify both $(location) expansions in the Bazel rule resolve to real files.
- Confirm the upstream compile produced the input file.
- Prefer running the Bazel target rather than the script directly.
Example fix
// before node javascript/atoms/typescript/wrap-find-elements-as-global.js find-elements.compiled.js // after node javascript/atoms/typescript/wrap-find-elements-as-global.js find-elements.compiled.js find-elements.global.js
Defensive patterns
Strategy: validation
Validate before calling
const [inputPath, outputPath] = process.argv.slice(2)
if (!inputPath || !outputPath) {
console.error('Usage: wrap-find-elements-as-global.js <input.js> <output.js>')
process.exit(2)
} Prevention
- Pass both input and output paths.
- Verify Bazel $(location) expansions for both labels.
- Run the Bazel target rather than the script directly.
- Confirm upstream compile produced the input.
When it happens
Trigger: Running the script with zero or one argument. A Bazel macro that fails to substitute both $(location) labels for the findElements target. Passing undefined from a misconfigured rule.
Common situations: Editing the findElements atom BUILD file and dropping one path argument. Manual invocation during debugging. A target rename that breaks location expansion.
