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:

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>
