Our assertion fields and input parameters support expressions. If you are trying to use the mentioned input in an assertion field (Ex: Right side field in a property card assertion row) or as Rule Under Test input parameter directly, it would fail, as the mentioned string is not a valid expression. If your intent is for it to be treated as a string and not as an expression, it should be enclosed in double quotes and conflicting characters should be escaped so that it confirms to a standard string. For parameters, this can be done by clicking on the gear icon and editing the parameter value to form a valid string.
We have a 1.5MB Json file with lots of data in it. Making it a valid String in itself is a huge effort. Do we have a way using which the input parameter field can handle a String? if not any workaround for my situation?
Please find below the sample string i used as per your instructions but i am getting the below error in the activity when i execute the test case:
