HI,
What is the input data you provided for the function, "pxConvertStringToPage"?
Based on the function usage (below), it accepts a string in a specified format (xml or json).
This function adopts input data as a string in a specified format (xml or json) onto the target clipboard page and returns a status indicating success or failure as a Boolean.<br><br>
Parameters: <br>
targetPage: Target clipboard page to map the input data to<br>
data: Input data as a String<br>
format: An optional format of input data, valid values are xml and json, default is json<br><br>
Return:<br>
true or false indicating success or failure of the operation<br>
In case of error, 'errorMessage' param is set with an appropriate error message<br>
So, please double check the function input.
example:
@(Pega-RULES:Page).pxConvertStringToPage (tools, myStepPage, Param.jsonstring,"json")
Thanks,
Susan

Try add step Page-New targetPage before step with with pxConvertStringToPage . I've got similar issue on 7.3.1:
My datatype was O1T7RB-B73b-Data-Test with following fields:
- A: Text
- B: Text
- C: TrueFalse
- D: TrueFalse
- E: ValueList (Text)
Defined sample Activity which takes json as input param Param.testjson
It had just 2 steps:
step1: @(Pega-RULES:Page).pxConvertStringToPage(tools, Test, Param.testjson, "json")
step2: use values from Test page..
where Test=O1T7RB-B73b-Data-Test
Then on section I defined button to run my activity with testjson = {"A":"aa", "b":"bb", "C":"true", "D":true, "E":["e1","e2"]}
Observations:
- fields A, C, D and E were set correctly, so bool values works both with and without quotation marks
- field "B" was not set, because in testjson it is with lowercase.
Then I modified O1T7RB-B73b-Data-Test by adding Text and FieldGroup properties and then remove both of them.

After that pxConvertStringToPage stopped working and in text file exported from Tracer I saw:

I fixed it by adding step Page-New: Test before pxConvertStringToPage step. No there is no error and Test is filled as expected:
<pagedata>
<pzActivityParams>testjson=%7B%22A%22%3A%22aa%22%2C+%22b%22%3A%22bb%22%2C+%22C%22%3A%22true%22%2C++%22D%22%3Atrue%2C+%22E%22%3A%5B%22e1%22%2C%22e2%22%5D%7D</pzActivityParams>

It works only if the page is there in the clipboard. Thanks Surdm
