WebStorm - trying to open an old project folder, getting this message: Cannot attach project: null any ideas?

AI generated answer (using internal Slack threads):

It seems like you're encountering an issue with WebStorm when trying to open an old project folder. This issue might be related to the version of WebStorm and the plugin you're using. One of the users in the thread suggested that it could be a JDK problem. A potential solution was suggested by a user who recommended using WebStorm 2019.1.4 and the 2019.2 release of the plugin. You can manage the versions using JetBrains toolbox. You can find the instructions for adding the SuiteCloud IDE Plug-in to WebStorm in the Help section of WebStorm. Another user suggested using the SDF CLI as an alternative. Remember to ensure that the

.idea

directory is present in your project. The presence of certain directory components like

AccountConfiguration

,

FileCabinet

,

Objects

, etc. might be necessary for the SuiteCloud plugin to recognize that a SuiteCloud project was opened. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
