Install bpmn-js-properties-panel and camunda-bpmn-moddle packages and import

import propertiesPanelModule from 'bpmn-js-properties-panel';
import propertiesProviderModule from 'bpmn-js-properties-panel/lib/provider/camunda';
import camundaModdleDescriptor from 'camunda-bpmn-moddle/resources/camunda';

Hope it will be useful.

Have you included the Camunda model extension?

yes in line 14 15 16 17
thank you philipp

I am stuck with the same problem, hope someone help us!

Attaching screenshots of code is not helpful. I can’t read any of it. Luckily, you can use Markdown:

Maybe this will be helpful for someone.

Importing camunda properties from camunda-bpmn-moddle/resources/camunda using the format below will wrap your json into a default parameter

import * as camundaModdleDescriptor from 'camunda-bpmn-moddle/resources/camunda.json'

it is better to use this apporach

import camundaModdleDescriptor from 'camunda-bpmn-moddle/resources/camunda';

I also have same problem anybody please help me

This is not a code bug, its project setup issue.

If you are using Angular, Please follow the following steps

  1. Open your TSCONFIG.JSON file and
  2. Add the following two compiler options
    “resolveJsonModule”: true,
    “esModuleInterop”: true,

Example TSConfig.json

  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "resolveJsonModule": true,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "lib": [
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true

AppComponent Changes

  1. Open your AppComponent
  2. Change the camundaModdleDescriptor import statement
import * as camundaModdleDescriptor  from 'camunda-bpmn-moddle/resources/camunda.json';


import { default as camundaModdleDescriptor } from 'camunda-bpmn-moddle/resources/camunda.json';

You are spot on. This resolves the issue.
