Double Slash in Appium Endpoint URL When path Ends with Slash causing 404 Errors #4865

The _buildAppiumEndpoint() function constructs the Appium REST API endpoint URL using path from this.browser.options. However, if path ends with a trailing slash (/), it results in a double slash (//) in the final URL before "session".

Steps to Reproduce:
Set path as '/' in this.browser.options:

this.browser.options = {
    protocol: 'http',
    hostname: '127.0.0.1',
    port: 4723,
    path: '/' // Root path with a trailing slash
};
this.browser.sessionId = '123456';

Call _buildAppiumEndpoint().

The generated URL will be:
http://127.0.0.1:4723//session/123456
Issue: The double slash (//session/) cause API request failures with 404 error.

Resolution:
Modify _buildAppiumEndpoint() to remove any trailing slash from path before constructing the URL.

Fix:

_buildAppiumEndpoint() { 
    const { protocol, port, hostname, path } = this.browser.options;
    // Ensure path does NOT end with a slash to prevent double slashes
    const normalizedPath = path.replace(/\/$/, '') || '';  
    return `${protocol}://${hostname}:${port}${normalizedPath}/session/${this.browser.sessionId}`;
}

Fixed Output (Corrected URL):
http://127.0.0.1:4723/session/123456

✅ Now, the API request will work as expected without double slashes. 🚀
