Topic: mdbModal gives an error
duong do free asked 6 years ago
Dear supporter,
We are using mdbModal for displaying some messages. However we get the following error:
TypeError: Cannot read property 'backdrop' of undefined AppComponent.html:37 message:"Cannot read property 'backdrop' of undefined" ngDebugContext:DebugContext_ {view: Object, nodeIndex: 15, nodeDef: Object, …} ngErrorLogger:function () { … } stack:"TypeError: Cannot read property 'backdrop' of undefinedn at ModalDirective.showBackdrop (webpack-internal:///../../../../ng-mdb-pro/free/modals/modal.directive.ts:213:42)n at ModalDirective.show (webpack-internal:///../../../../ng-mdb-pro/free/modals/modal.directive.ts:122:14)n at ActivityCreateComponent.set [as show] (webpack-internal:///../../../../../src/app/activity-create/activity-create.component.ts:110:41)n at updateProp (webpack-internal:///../../../core/esm5/core.js:12826:37)n at checkAndUpdateDirectiveInline (webpack-internal:///../../../core/esm5/core.js:12533:19)n at checkAndUpdateNodeInline (webpack-internal:///../../../core/esm5/core.js:14100:20)n at checkAndUpdateNode (webpack-internal:///../../../core/esm5/core.js:14043:16)n at debugCheckAndUpdateNode (webpack-internal:///../../../core/esm5/core.js:14936:76)n at debugCheckDirectivesFn (webpack-internal:///../../../core/esm5/core.js:14877:13)n at Object.eval [as updateDirectives] (ng:///AppModule/AppComponent.ngfa... __proto__:Error {constructor: , name: "TypeError", message: "", …}
We look into the code and see that it uses "this.config.backdrop" when this.config is undefined.
rule 259 of modal.directive.ts
if (this._isShown && this.config.backdrop && (!this.backdrop || !this.backdrop.instance.isShown)) {
Is it a well-known error?

Dear Duong, This isn't a known error for us. Could you provide me some reproduction steps? Could you try to try catch this block of code? Maybe it will help. Best Regards, Damian
