I found these snippets:

https://psalm.dev/r/7e3d196de1
<?php

/**
 * @psalm-type HttpOptions = array{
 *   headers?: array<string, string | list<string>>,
 * }
 *
 * @psalm-type SerializedAccount = HttpOptions & array{discoveryUri: string, baseUrl?: ?string}
*/

/**
 * @psalm-param SerializedAccount $props
 */
function constructFromArray(array $props): string
{
    $requiredProps = [ 'discoveryUri' ];
    
    foreach ($requiredProps as $prop) {
        if (!isset($props[$prop])) {
            throw new \Exception("x");
        }
    }

    return $props["discoveryUri"];
}

/**
 * @psalm-param SerializedAccount $props
 */
function constructFromArray2(array $props): string
{
    return $props["discoveryUri"];
}
Psalm output (using commit ef3b018):

ERROR: InvalidReturnStatement - 24:12 - The inferred type 'array<string, list<string>|string>|string' does not match the declared return type 'string' for constructFromArray

ERROR: InvalidReturnType - 14:44 - The declared return type 'string' for constructFromArray is incorrect, got 'array<string, list<string>|string>|string'
