This code seems to be duplicated across your project.

			$guid = $statement;
		} elseif ( $statement instanceof StatementGuid ) {
			$guid = $statement->getSerialization();

The method Wikibase\DataModel\Statement\StatementGuid::getSerialization() has been deprecated with message: The value returned by this method might differ in case from the original, unparsed statement GUID
(the entity ID part might have been lowercase originally, but is always normalized in the return value here),
which means that the value should not be compared to other statement GUID serializations,
e.g. to look up a statement in a StatementList.

		} elseif ( $statement instanceof Statement ) {
			$guid = $statement->getGuid();
		} else {
			throw new UnexpectedValueException( 'Could not get statement guid from $statement' );
		}
		if ( !is_string( $guid ) ) {
			throw new UnexpectedValueException( 'Unexpected statement guid got from $statement' );
		}

		$referenceSerialization = $this->referenceSerializer->serialize( $reference );

		$params = [
			'statement' => $guid,
