I am currently working in a company where I have to fix a couple issue with IE11. One of the issues is only present in IE11 which centers around uuidv4 from node_modules.
the code at fault and the error that I am seeing is
Syntax error in regular expression
/***/ (function (module, exports, __webpack_require__) {
"use strict";
//eval("
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : {"default": mod };};
Object.defineProperty(exports, "__esModule", { value: true });
const v4_1 = __importDefault(__webpack_require__(/*! uuid/v4 */ "../node_modules/uuid/v4.js"));
const v5_1 = __importDefault(__webpack_require__(/*! uuid/v5 */ "../node_modules/uuid/v5.js"));
const uuidv4 = function () {
return v4_1.default();
};
uuidv4.regex = {
v4: /^(?:[a-f0-9]{8}-[a-f0-9]{4}-4[a-f0-9]{3}-[a-f0-9]{4}-[a-f0-9]{12})|(?:0{8}-0{4}-0{4}-0{4}-0{12})$/u,
v5: /^(?:[a-f0-9]{8}-[a-f0-9]{4}-5[a-f0-9]{3}-[a-f0-9]{4}-[a-f0-9]{12})|(?:0{8}-0{4}-0{4}-0{4}-0{12})$/u
}; uuidv4.is = function (value) {
return uuidv4.regex.v4.test(value) || uuidv4.regex.v5.test(value);
}; uuidv4.empty = function () {
return '00000000-0000-0000-0000-000000000000';
};
uuidv4.fromString = function (text) {
const namespace = 'bb5d0ffa-9a4c-4d7c-8fc2-0a7d2220ba45';
const uuidFromString = v5_1.default(text, namespace);
return uuidFromString;
};
exports.default = uuidv4;
//# sourceURL=webpack://_chex/../node_modules/uuidv4/build/lib/uuidv4.js?");
/***/
}),
I did see and look to resolve what could have been one of the problems in the code in here changing
v5: /^(?:[a-f0-9]{8}-[a-f0-9]{4}-5[a-f0-9]{3}-[a-f0-9]{4}-[a-f0-9]{12})|(?:0{8}-0{4}-0{4}-0{4}-0{12})$/u
to
v5: /^(?:[a-f0-9]{8}-[a-f0-9]{4}-4[a-f0-9]{3}-[a-f0-9]{4}-[a-f0-9]{12})|(?:0{8}-0{4}-0{4}-0{4}-0{12})$/u
{4}-5 was the offending item in this regex, however IE11 still complains about the same issue.
But on closer inspection this is the line that it is complaining about
v4: /^(?:[a-f0-9]{8}-[a-f0-9]{4}-4[a-f0-9]{3}-[a-f0-9]{4}-[a-f0-9]{12})|(?:0{8}-0{4}-0{4}-0{4}-0{12})$/u,
When trying to put debugger statements in place, I cant hit these as before I get there and the code is being evaluated it fails and produces the error.
Any and all help on this will be gratefully received.
