Parameter does not exist in report

 The following error occurs when a parameter value is saved in the report xml and is not on the design of the report. 

If we observe the design of the report we can notice that the parameter "SPYPERFREVIEWLISTREPO_DynamicParameter" which is reported missing does not exist on the design. Which means that the design did not sync with the XML and this parameter is still being referred with an incorrect parameter name. 

To fix this error we open the report in XML layout and replace the parameter name with "SPYPERFREVIEWDETAILSR_DynamicParameter" in this case as this is the actual name of the parameter.
