I have an issue with SSRS. I deleted a parameter and it’s not in my report but I have this error:

The ‘Value’ expression for the query parameter ‘xxx’ refers to a non-existing report parameter ‘xxx’. Letters in the names of parameters must use the correct case.

How can I resolve it?

Thank you,

I deleted all the expressions that refer to this parameter in the report, I expected the error to disappear but it’s still present
