> **NOTE**
>
> This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](../errorcode-universal.md).

## 11100001 Application Event Logging Disabled

**Error Message**

Function disabled.

**Description**

- The **write** API is called to perform application event logging, but the system ignores related events because the logging function is disabled.
- The **setEventParam** API is called to set custom event parameters, but the system ignores the calling because the logging function is disabled.

**Possible Causes**

The application event logging function is disabled.

**Solution**

Invoke the **configure** API to enable the application event logging function.

   ```ts
   import hiAppEvent from '@ohos.hiviewdfx.hiAppEvent';

   hiAppEvent.configure({
       disable: false
   });
   ```

## 11101001 Invalid Event Domain Name

**Possible Causes**

The specified event domain name does not comply with the following rules:

- The event domain name contains only digits, letters, and underscores (\_).
- The event domain name starts with a letter and does not end with an underscore (\_).

## 11101003 Invalid Number of Event Parameters

**Error Message**

Invalid number of event parameters.

**Description**

This error code is reported if the **write** API is called to perform application event logging but the system discards extra event parameters because the number of input event parameters exceeds the limit.

**Possible Causes**

The number of input event parameters exceeds 32.

**Solution**

Specify a valid number of event parameters.

## 11101004 Invalid Event Parameter String Length

**Error Message**

Invalid string length of the event parameter.

**Description**

- The **write** API is called to perform application event logging, but the system ignores related event parameters because the value of the input event parameter is excessively long.
- The **setEventParam** API is called to set custom event parameters, but the system ignores the calling because the input event parameter value is invalid.

**Possible Causes**

- The length of the string of the event parameter value passed by the **write** API exceeds 8 x 1024 characters.
- The length of the custom event parameter value passed by the **setEventParam** API exceeds 1024 characters.

**Solution**

Specify an event parameter value with a valid length.

## 11101005 Invalid Event Parameter Name

**Error Message**

Invalid event parameter name.

**Description**

- The **write** API is called to perform application event logging but the system ignores related event parameters because the input event parameter name is invalid.
- The **setEventParam** API is called to set custom event parameters, but the system ignores the calling because the input event parameter name is invalid.

**Possible Causes**

The specified event parameter name does not comply with the following rules:

- The event parameter name contains only the dollar sign ($), digits, letters, and underscores (_).
- The event parameter name must start with a letter or dollar sign ($) and end with a digit or letter.
- The event parameter name is not empty and contains a maximum of 32 characters.

**Solution**

Specify a valid event parameter name.

## 11101006 Invalid Array Length of Event Parameter Values

**Error Message**

Invalid array length of the event parameter.

**Description**

This error code is reported if the **write** API is called to perform application event logging but the system discards extra array elements because the array of the event parameter value is excessively long.

**Possible Causes**

The array length of the event parameter value exceeds 100.

**Solution**

Specify a valid array length for the event parameter value.

## 11101007 Invalid Number of Custom Event Parameters

**Error Message**

The number of parameter keys exceeds the limit.

**Description**

The **setEventParam** API is called to set custom event parameters, but the system ignores the calling because the number of event parameters is invalid.

**Possible Causes**

The number of custom event parameters passed exceeds 64.

**Solution**

Specify a valid number of custom event parameters.

## 11102001 Invalid Watcher Name

**Error Message**

Invalid watcher name.

**Description**

This error code is reported if the **addWatcher** API is called to subscribe to application events but the system ignores the subscription because the specified watcher name is invalid.

**Possible Causes**

The specified watcher name does not comply with the following rules:

- The watcher name can contain only digits, letters, and underscores (\_).
- The watcher name starts with a letter and does not end with an underscore (\_).
- The watcher name is not empty and contains a maximum of 32 characters.

**Solution**

Specify a valid watcher name.

## 11102002 Invalid Filtering Event Domain Name

**Error Message**

Invalid filtering event domain.

**Description**

This error code is reported if the **addWatcher** API is called to subscribe to application events but the system ignores the subscription because the specified filtering event domain name is invalid.

**Possible Causes**

The specified filtering event domain name does not comply with the following rules:

- The event domain name contains only digits, letters, and underscores (\_).
- The event domain name starts with a letter and does not end with an underscore (\_).
- The event domain name is not empty and contains a maximum of 32 characters.

**Solution**

Specify a valid filtering event domain name.

## 11102003 Invalid Event Number

The event number passed in the input callback triggering condition is a negative number.

**Solution**

Specify a valid event number.

## 11102004 Invalid Event Size

**Error Message**

Invalid size value.

## 11103001 Invalid Maximum Storage Quota

**Error Message**

Invalid max storage quota value.

**Description**

This error code is reported if the **configure** API is called to subscribe to application events but the system ignores the setting because the specified maximum storage quota is invalid.

The maximum storage quota does not meet the following rules:

- The quota value consists of only digits and a unit (including b|k|kb|m|mb|g|gb|t|tb, which are case-insensitive).
- The quota value must start with a digit. You can determine whether to pass the unit. If the unit is left empty, **b** (that is, byte) is used by default.

**Solution**

Specify a valid maximum storage quota.

## 11104001 Invalid Event Package Size

**Error Message**

Invalid size value.

**Description**

This error code is reported if the **setSize** API is called to set the threshold of the event package size but the system ignores the setting because the specified event package size is invalid.
