Error: 'type' while using CSS Selector Extraction Strategy

[franjefriten]

I am using CSS Selector for Extration Strategy to get certain data from this website inside div#convocatoriasEmpleoActivas. This is the struvture of my json format css selector:

schema = {
        "name": "Convocatoria",
        "baseSelector": "div#convocatoriasEmpleoActivas",    # Repeated elements
        "fields": [
            {
                "name": "convocatoria",
                "selector": "h1",
                "type": "text"
            },
            {
                "name": "puesto",
                "selector": "p.puesto span",
                "type": "text"
            },
            {
                "name": "fecha_publicación",
                "selector": "p.fecha span",
                "type": "text"
            },
            {
                "name": "plazo",
                "selector": "p.plazos",
                "fields": [
                    {
                        "name": "inicio",
                        "selector": "span.inicio",
                        "type": "text"
                    },
                    {
                        "name": "fin",
                        "selector": "span.fin",
                        "type": "text"
                    }
                ]
            },
            {
                "name": "entidad",
                "selector": "p.organoInstructor span",
                "type": "text"
            },

        ]
    }

and this is the code for the extraction strategy:

    keyword_scorer = KeywordRelevanceScorer(
        keywords=["ayudas", "convocatorias", "premios", "subvenciones", "Portal", "PortalAyudas", "accion", "opportunities"]
    )
    filter_chain = FilterChain([
        # Only follow URLs with specific patterns
        URLPatternFilter(patterns=[
            r"^https://www.ciencia.gob.es/Convocatorias/*",
        ]),

        # Only crawl specific domains
        # DomainFilter(
            # allowed_domains=["https://www.pap.hacienda.gob.es"],
        # ),

        # Only include specific content types
        ContentTypeFilter(allowed_types=["html"])
    ])
    deep_crawl_strategy = BestFirstCrawlingStrategy(
        max_depth=1,
        include_external=True,
        url_scorer=keyword_scorer,
        logger=logger,
        filter_chain=filter_chain
    )
    schema = ...
    extraction_strategy = JsonCssExtractionStrategy(schema=schema, logger=logger, verbose=True)
    run_config = CrawlerRunConfig(
        deep_crawl_strategy=deep_crawl_strategy,
        scraping_strategy=LXMLWebScrapingStrategy(logger=logger),
        extraction_strategy=extraction_strategy
    )
    browser_config = BrowserConfig(
        verbose=True,
        accept_downloads=True,
        java_script_enabled=True,
        ignore_https_errors=True,
    )

However, I am getting an error like this

I have delved into the source code of crawl4ai and try to figure out why this is the case. But I can't seem to find any reason why, as there is a "type" key in my json string. I have followed docs meticulously but i can't seem to find the solution. I tried to change "type" to "computed", but I have the same error. By the way, this is my first issue, so please be mindful about my unintended boldness.
