   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.
