# PerfTest Error Codes > **NOTE** > > This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](../errorcode-universal.md). ## 32400001 Initialization Failed **Error Message** Initialization failed. **Description** The framework fails to be initialized. **Possible Causes** The bundle name of the application cannot be obtained. **Solution** Run the **ps** command to check whether the application process exists. Ensure that the application process exists. ## 32400002 Internal Error **Error Message** Internal error. **Description** An internal error occurs in the framework. **Possible Causes** 1. IPC transmission fails. 2. The **PerfTest** object does not exist. **Solution** 1. Retry the IPC transmission. 2. Check whether the **PerfTest** object has been destroyed. If yes, create a **PerfTest** object again. For details, see the [create](js-apis-perftest.md#create) API. ## 32400003 Parameter Verification Failed **Error Message** Parameter verification failed. **Description** Parameter verification failed. **Possible Causes** The parameter type is incorrect or the parameter value is out of the specified range. **Solution** Check whether the input parameters of the API meet the requirements. ## 32400004 Failed to Execute the Callback **Error Message** Failed to execute the callback. **Description** Failed to execute the callback. **Possible Causes** 1. An exception is thrown in the callback. 2. The callback execution times out. **Solution** Check the internal logic of the callback to ensure that no exception is thrown and that the callback execution does not time out. ## 32400005 Failed to Collect Performance Data **Error Message** Failed to collect metric data. **Description** Failed to collect performance data. **Possible Causes** The application process does not exist during performance data collection. **Solution** Run the **ps** command to check whether the application process exists during performance data collection. Ensure that the application process exists. ## 32400006 Failed to Obtain Performance Data **Error Message** Failed to obtain the measurement result. **Description** Failed to obtain the test data of the specified performance metric. **Possible Causes** The data collection is not complete. **Solution** Ensure that the [PerfTest.run](js-apis-perftest.md#run) API has been executed and no exception is thrown. Ensure that the data collection is complete before obtaining the specified data. ## 32400007 API Does Not Support Concurrent Calls **Error Message** The API does not support concurrent calls. **Description** The API does not support concurrent calls. **Possible Causes** The async API does not use **await** to wait until the asynchronous execution is complete. As a result, the API is called concurrently. **Solution** Use **await** to wait until the asynchronous function execution is complete.
