Marianne Abdelmalek opened SPR-15740 and commented

Although the documentation states that:

/**
	 * Return the first query parameter with the given name, if present.
	 * @param name the parameter name
	 * @return the parameter value
	 */
	default Optional<String> queryParam(String name) {
		List<String> queryParams = this.queryParams(name);
		return (!queryParams.isEmpty() ? Optional.of(queryParams.get(0)) : Optional.empty());
	}

which returns Optional, it throws null pointer exception when the query param is not present.
The line that throws the null pointer exception is:

//req is of type ServerRequest
req.queryParam("page")

It used to work properly days ago, I guess you guys changed something. Please check.
