export is only valid in ES Module syntax. When the file is run as CommonJS, an Unexpected token export error may occur if the old runtime does not recognize modern syntax or if the test runner has not converted the ESM package in node_modules.

Unexpected token export in node_modulesexport is only valid in ES Module syntax. When the file is run as CommonJS, an Unexpected token export error may occur if the old runtime does not recognize modern syntax or if the test runner has not converted the ESM package in node_modules.
A SyntaxError may stop all subsequent scripts; First resolve the first red record in the Console.
Determine whether the error is source or build with Source map, pretty print and Network URL.
Reduce the issue to a small area with node --check, ESLint, TypeScript or JSON validator.
Check the PHP render, API body, CDN cache and module loader result in the production answer.
Do not edit the node_modules file as a permanent solution.
Meaning: File is being parsed as export while not being an ESM.
Possible cause: CommonJS working mode.
Meaning: Test runner ESM dependency is not being converted.
Possible cause: transformIgnorePatterns or ESM setting.
Meaning: Dependency only published ESM.
Possible cause: Old Node or CommonJS consumer.
Meaning: The transpile setting is leaving module syntax.
Possible cause: Preset/target configuration.
Meaning: tsc module hedefi runtime ile uyumsuz.
Possible cause: module esnext, Node CommonJS.
Meaning: The Vite/Webpack source file is being run directly with node.
Possible cause: Incorrect npm script.
Meaning: Sub package.json defines different type.
Possible cause: Monorepo limit.
Meaning: Syntax is valid but import method is incorrect.
Possible cause: difference between default/named.

node --check dist/index.jsVerifies the actual build file to be executed.
node -e "const p=require('./package.json'); console.log(JSON.stringify({type:p.type,main:p.main,module:p.module,exports:p.exports},null,2))"Displays the package's module entries.
npx tsc --showConfig | grep -iE 'module|target|moduleResolution'Displays the compiler's actual module settings.
node -e "const p=require('./node_modules/PACKAGE/package.json'); console.log(p.type,p.main,p.module,p.exports)"The problematic package shows its ESM/CommonJS information.
npx jest --showConfig > jest-config.jsonJest's active transform and ESM settings are exported to the file.
rm -rf dist node_modules/.cache && npm run build && node --check dist/index.jsClear the old cache and re-check the build output.

Node version, package.json module type, build output, and the actual file run should comply with the same module system.
PHP warnings, theme HTML, redirects, and double script loading JavaScript errors may appear.
It occurs when the JavaScript parser, JSON parser, or module loader cannot find the expected grammar.
The line is usually where the parser detects the error. Missing quotes, parentheses, or commas may be in the previous line.
Use source map and DevTools pretty print; correct the original source file and rebuild.
PHP warning, HTML error page or unpadded data pressed may break JavaScript/JSON syntax.
Most parsers find most errors; however, incorrect server response, double script loading, and runtime module configuration should also be checked.
Deploy, minify, cache, package update, Node version, PHP output or half-loaded file behavior may have changed.
Provides diagnostic and safe repair steps; changes should be tested in the staging environment and reverted using Git.
We examine Console, Fetch/AJAX, PHP JSON responses, ES Modules, TypeScript build and WISECP script loading problems without disrupting the production structure.
