Why do I get the error “JavaScript heap out of memory” during deployment?
Increase the heap memory by setting the environment variable NODE_OPTIONS=–max-old-space-size=4096.

App Platform automatically obfuscates emails in a site’s HTML to protect against accidental leaks of personal information.
To disable this feature, update your app spec with the following:
disable_email_obfuscation: "true"
For a full example of an app spec, see the App Spec Reference.
Increase the heap memory by setting the environment variable NODE_OPTIONS=–max-old-space-size=4096.
Delete the existing dev database and create a new one. Then make sure that the app deployment completes successfully.
You cannot add the same domain name to multiple apps or split an app and domain name across more than one account.
Try using different keywords or simplifying your search terms.
