It seems like there might be some type compatibility issues in your code. The error you're encountering is related to the type of the `customRenderInput` function not matching the expected type `RenderInputCallback<InputProps>`.

The error message also indicates that there is a mismatch between the expected `NumberInputProps<NumberSchemaType>` and the actual type `Omit<InputProps, "renderDefault">`.

To resolve this, you may need to ensure that the types are aligned correctly. Without having the full context of your code, I can provide a general suggestion. It looks like you might be trying to create a custom input renderer for a form component. Here's a possible way to adjust your code to align with the expected types:

const customRenderInput: RenderInputCallback<InputProps> = useCallback(
  (inputProps: InputProps) => {
    const { value } = inputProps; // Assuming value is present in InputProps
    
    // Add a label showing the current value of 'mediaType'
    return (
      <Stack>
        {/* Call the original renderInput function, passing along input props */}
        <CustomStringInput
          {...(inputProps as StringInputProps)} // You might need to cast to the appropriate type here
        />
        <Flex paddingTop={2} justify="flex-end">
          <Text size={1} muted>
            <em>({value?.mediaType && `Type: ${value.mediaType}`})</em>
          </Text>
        </Flex>
      </Stack>

Please adjust the code according to your specific requirements and types. Make sure that the types of `inputProps` and the type you are casting to (`StringInputProps` or similar) are correctly aligned. If the issue persists, it might help to provide more context or specific code snippets related to the `CustomStringInput` and other relevant parts of your code.
