Unclear REST service endpoint content type for /dictionary

[zambrovski]

Environment Details

• EclipseStore Version: 1.1.0
• JDK version: 17
• OS: ubuntu 22.04
• Used frameworks: Spring, SparkJava

Describe the bug

Implementing the endpoints for restservice-spring I realized that there is a "contradiction" in the docs and the implementation. The docs of the REST API says:

Returns the type dictionary as plain text.

In fact it is a plain text, since its return type is a plain string:

0000000000000000001 byte{
	primitive 8 bit integer signed,
}
0000000000000000002 boolean{
	primitive 8 bit boolean,
}
0000000000000000003 short{
	primitive 16 bit integer signed,
}

and so on

If I look on the implementation of the SparkJava Rest Service the response type is set to application/text (I believe this doesn't exist as contentType)

At the same time, the Jersey Client expects the content type to be application/json.

Expected behavior

Clarify which content type should be delivered.
