module: fix crash on multiline named cjs imports
The node process crashes when trying to parse a multiline import statement for named exports of a CommonJS module: TypeError: Cannot read property '0' of null at ModuleJob._instantiate (internal/modules/esm/module_job.js:112:77) at async ModuleJob.run (internal/modules/esm/module_job.js:137:5) at async Loader.import (internal/modules/esm/loader.js:165:24) at async rejects.name (file:///***/node/test/es-module/test-esm-cjs-named-error.mjs:56:3) at async waitForActual (assert.js:721:5) at async rejects (assert.js:830:25), The reason is that the regexp that is currently used to decorate the original error fails for multi line import statements. Unfortunately the undecorated error stack only contains the single line which causes the import to fail: file:///***/node/test/fixtures/es-modules/package-cjs-named-error/multi-line.mjs:2 comeOn, ^^^^^^ SyntaxError: The requested module './fail.cjs' does not provide an export named 'comeOn' at ModuleJob._instantiate (internal/modules/esm/module_job.js:98:21) at async ModuleJob.run (internal/modules/esm/module_job.js:141:5) at async Loader.import (internal/modules/esm/loader.js:165:24) at async rejects.name (file:///***/node/test/es-module/test-esm-cjs-named-error.mjs:56:3) at async waitForActual (assert.js:721:5) at async rejects (assert.js:830:25) Hence, for multiline import statements we cannot create an equivalent piece of code that uses default import followed by an object destructuring assignment. In any case the node process should definitely not crash. So until we have a more sophisticated way of extracting the entire problematic multiline import statement, show the code example only for single-line imports where the current regexp approach works well.
