Unrecognized escape sequence \I

[AviramDahan]

Error:
Unrecognized escape sequence \I

Has anyone encountered this error before while parsing the AreaMap?

	  "AreaMaps": {
	     "Test1\\Internet\\Machine Learning": "Target1\\Target2"
	  },

The Iteration Maps and Area Maps documentation covers this:

Warning: Special characters in the acceptation of regular expressions and json both need to be escaped. For a key, this means, for example, that a literal backslash must be escaped for the regular expression language \\ and each of these backslashes must then be escaped for the json encoding: \\\\. In the replacement string, a literal $ must be escaped with an additional $ if it is followed by a number (due to the special meaning in regular expression replacement strings), while a backslash must be escaped (\\) due to the special meaning in json.

So your notation needs to be:

"AreaMaps": {
	     "Test1\\\\Internet\\\\Machine Learning": "Target1\\Target2"
	  },
