Try this: 
Kill the process running on port 1717 or use a custom connected app and update OauthLocalPort in the sfdx-project.json file.

Hi,

i get an UNABLE_TO_LOCK_ROW  error when running my tests in parallel. The error occurs when creating a pricebookentry in the standard pricebook. As far as i know Salesforce locks also the parent Object when inserting a object. Which would mean that in this case while inserting the pricebookentry the pricebook is locked. When now a parallel test wants to add another entry to the locked pricebook the test throws the UNABLE_TO_LOCK_ROW error.

Does anyone know how to get around this?

Can any body help me what are the differences between SOAP API and REST API..?

and, below is my code to set field values, which I retrieved from a POJO object.

 

    public MessageElement createNewXmlElement(String Name, String nodeValue) throws Exception {

        MessageElement msgElement;
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.newDocument();
        
        Element xmlEle = document.createElement(Name);
        xmlEle.appendChild(document.createTextNode(nodeValue));

        msgElement = new MessageElement(xmlEle);

        return msgElement;
    }

 

I found similar issue in the forum and I am sure, I never called getUserinfo method before the session created. Can anyone help me out from this issue.

 

Regards,

SuBaa
