Error while creating a project in STS - JSONException: A JSONObject text must begin with '{' at character 0

Recently while trying to create a Spring Boot project in my IDE i.e. Spring Tool Suite(STS, Version:3.9.2.RELEASE) using Spring Starter Project, I have got an error.

Replication Steps: In STS, navigated to File -> New -> Spring Starter Project, and as soon as I clicked on it, I got the error. The errors state that :

JSONException: A JSONObject text must begin with '{' at character 0

 Today I would be sharing the workaround and solution that worked for me. It might help someone who faces a similar issue while creating projects using their IDE.

Workaround & Solution:

Through STS, when anyone tries to create a Spring project then it internally uses Spring Initializr ( which is a quickstart generator for Spring projects. It simply means we have a workaround for this problem i.e. generating the project from our browser by accessing, downloading a ZIP of the project, unpacking it locally and at last, importing it using "Import -> Maven -> Existing Maven Project" into STS.

The above workaround should surely work for everyone. It also suggests that our IDE i.e. STS is unable to connect with  and this is the root cause of this issue. But how to establish this connection, don't worry just follow the below steps:

Step 1: From STS navigate to Window -> Preferences -> General -> Network Connections
Step 2: In Network Connections, select 'Direct' from Active Provider dropdown and click on 'Apply and Close' button. Choosing Direct causes all the connections to be opened without the use of a proxy server.
Step 3: Now give it a try, create the project using STS i.e. File -> New -> Spring Starter Project.

It should work for you as well.
For reference,

Let me know in the comment section if the workaround and solution have worked for you or not. Happy Learning!!
