And I see the same issue.
My code:
{
By img = null;
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
try {
img = AppiumBy.image(new ImageUtil().getReferenceImageB64(“popup/dismissButton.png”));
} catch (URISyntaxException | IOException e) {
throw new RuntimeException(e);
}
wait.until(ExpectedConditions.presenceOfElementLocated(img)).click();
}

and :
public String getReferenceImageB64(String fileName) throws URISyntaxException, IOException {
URL refImgUrl = getClass().getClassLoader().getResource(fileName);
File refImgFile = Paths.get(refImgUrl.toURI()).toFile();
return Base64.getEncoder().encodeToString(Files.readAllBytes(refImgFile.toPath()));
}
