Report deployment error "Sequence contains no matching element"

 Sometimes when we change the source query of the datasets and redeploy the report we can get the error "Sequence contains no matching element"

It turned out that during the dataset restore a parameter was added. It was added at the Parameters node at the report level and the node Parameters, however if one of the parameters is deleted then this error will occur. 

So, this error occurs if a parameter name is being referred to at the dataset level and the same parameter does not exist at the report level. 

To resolve this error ensure that each parameter at the dataset level is mapped to a parameter at the report level. Also use dynamic parameters only for one dataset and not for multiple.

If the error still exists then try to recollect the parameters that you have lately modified and check if a reference for them still exists in the XML file and try to manually resolve them and map them to the newly updated parameters. Search QueryParameter in the XML and check the parameters individually for each dataset and report to identify any incorrect value and accordingly correct or remove the value from XML.

Sometimes this error can also occur is a report was deployed with Dynamic Parameter and then was changed to have Dynamic Parameter to false. In such cases make sure that you enable the dynamic parameter for the first dataset and then try to deploy again.
