I am working on an assignment where the phone number of a contact will be passed via the URL. I have developed a lightning tab, associated with a Lightning component with the corresponding js controller, helper and apex controller and the functionality is working fine from the development sandbox where I have developed. Now, I deployed the components to the QA sandbox and when I try the QA URL (exactly in the same format as the DEV URL), I am getting a "Page doesn't exist" error. A screenshot is given below.
RPCMemberSearch is the lightning tab associated with the lightning component RPCMemberSearch.cmp. The DEV URL parses the phone number, queries salesforce, and lists the contacts if there are multiple contacts. If there is a single contact, the contact page will be displayed. If there are no contacts associated with the supplied phone number, a message will be displayed accordingly and "Goto Home" button will be available. All this works fine in DEV, but not in QA. Can some one help? I am not sure if this is related to Summer 18 release that was pushed by Salesforce over the weekend.
FYI, I have not developed a separate app for this.
