Jindřich Bär (jindrich.bar)

Hello and thank you for your interest in this Actor!

I apologize for the frustration this issue has caused.

The preNavigationHooks field in the Web Scraper actor expects a string in the JSON configuration. This string should contain the JavaScript code that specifies an array of functions. For example:

"preNavigationHooks": "[    async (crawlingContext) => {    console.log('first pre hook', crawlingContext.request.url);    },    async (crawlingContext) => {     console.log('pre hook2', crawlingContext.request.url);    }]"

At runtime, this string is evaluated to create the required array of functions. If the format is not correct, you may see errors like the ones you mentioned. Please ensure the input follows the format above to avoid these issues.

We’re working to make these requirements more consistent and user-friendly. For example, you can use the code editor on the Input tab in the Apify Console to set this up (and then just copy the JSON input to your script). The code editor provides a better user experience with code highlighting and automatic JavaScript syntax checking.

I’m closing this issue now, but feel free to reach out if you need further assistance. Thank you for your patience and understanding!
