Problem adding Context context parameter to idstore and event endpoints

[MavenRain]

When attempting to add a context parameter, the compiler complained about the Context type not implementing Decode, when this has not happened for other ledger endpoints.

For example: Changing

fn get_from_recall_phrase(
        &self,
        args: idstore::GetFromRecallPhraseArgs,
    ) -> Result<idstore::GetReturns, ManyError>

to

fn get_from_recall_phrase(
        &self,
        args: idstore::GetFromRecallPhraseArgs,
        context: Context
    ) -> Result<idstore::GetReturns, ManyError>

reproduces the compiler error mentioned.
