I am now getting the following error: An unknown server-side error occurred while processing the command. Original error: Cannot read properties of undefined (reading ‘element’)`
My code:
async scrollDirection(startCoordinates: { x: number; y: number; }, endCoordinates: { x: number; y: number; }) {
const touchActionPromise = driver.touchPerform([
{ action: 'press', startCoordinates },
{ action: 'moveTo', endCoordinates },
{ action: 'release' }
]);
const timeoutPromise = new Promise((resolve) => setTimeout(resolve, 2000, 'Touch Action Timeout'));
await Promise.race([touchActionPromise, timeoutPromise]);
}
async scrollIntoView(maximumScrolls = 2) {
const scrollScreenSize = async (direction) => {
const { width, height } = await driver.getWindowRect();
const startCoordinates = { x: width / 2, y: height / 2 };
let endCoordinates;
const scrollRatio = 1.0; // Adjust this value to increase or decrease scroll length
if (direction === 'down') {
endCoordinates = { x: width / 2, y: height * (1 - scrollRatio) };
} else if (direction === 'up') {
endCoordinates = { x: width / 2, y: height * scrollRatio };
}
await this.scrollDirection(startCoordinates, endCoordinates);
};
let element = await $(this.selector);
for (let scrolls = 0; scrolls < maximumScrolls; scrolls++) {
if (await element.isDisplayed()) return; // Exit if element is visible
const direction = scrolls < maximumScrolls / 2.5 ? 'down' : 'up';
await scrollScreenSize(direction);
element = await $(this.selector);
}
// If element not found after all scrolls
throw Error(`Could not find screen element '${this.elementName}' while attempting to scroll the element into view, with the maximum retries of ${maximumScrolls}. Searching by selector: ${this.selector}`);
}
I have tried with updrading and downgrading the version of the following: “appium”: “2.3.0”, “appium-uiautomator2-driver”: “2.37.0”,
Have tried changing the scrolling implementation, but always results in the same issue.
The code works perfectly fine for iOS.
