Cannot read properties of undefined (reading 'context')

[hosseintalebi]

I'm trying to use RollbarContext and it's giving me an error on its componentDidMount function as it's trying to access rollbar.options.payload.context (see here). Looking at the rollbar.options object, there's no payload.

This is how I'm using the <RollbarContext>:

const rollbarConfig = {
  accessToken: '<token>',
  environment: 'testenv',
};
...
    <Provider config={rollbarConfig}>
       <ErrorBoundary>
        <Router>
          <Route path={rootPath}>
            <Switch>
              {Object.entries(routes).map(([path, route]) => {
                return (
                  <RollbarContext context={path}>
                    <LazyRoute ... />
                  </RollbarContext>
                );
              })}
              <Redirect from="*" to="/app/404" />
            </Switch>
          </Route>
        </Router>
      </ErrorBoundary>
    </Provider>

I'm using the following versions of the libraries:

• [email protected]
• @rollbar/[email protected]

Running into the same issue, here's my usage:

const Chat: React.FC = () => {
  useRollbarContext('chat#list')

  return (
    <IonPage>
      <Header title='Chat' />
      <IonContent>
        <CometChatConversationsWithMessages
          isMobileView={true}
          messagesConfiguration={messageConfig}
          conversationsConfiguration={conversationConfig}
        />
      </IonContent>
    </IonPage>
  )
}

export default Chat

I have a similar issue.

`
const rollbarConfig = {
accessToken: 'xxxxx',
environment: 'production',
};
export default function App() {
return (

            <Router>
                <div>
                  
                       <Provider config={rollbarConfig}>
                           <ErrorBoundary
                               fallbackUI={ErrorBoundaryMessage}
                           >
                                <Suspense fallback={<LoadingAdvice/>}>
                                    <Switch>
                                        <Route path="/register/start/:guid">
                                           <RollbarContext context={'registerStart'} >
                                                <RegisterStart />
                                            </RollbarContext>
                                        </Route>
                                        

                                    </Switch>
                                </Suspense>
                           </ErrorBoundary>
                       </Provider>
                </div>
            </Router>
        </ThemeProvider>
    </StyledEngineProvider>
);

}

I came across this same issue as well, using: @rollbar/react: 0.11.2, rollbar: 2.26.4

I think the Rollbar library should be able to set a default payload if none is provided in the initial config.

Workaround:

Setup the Provider to have a default value in the config for payload.

import { Provider } from '@rollbar/react';

// ...

<Provider
  config={{
    enabled: true,
    payload: {},
  }}
>

as long as the payload object is defined initially, then setting a context later will not throw an error.
