Web SDK Not Found Error When Testing Locally

[lnl669]

Hi Community,

I am trying to implement the Adobe Experience Platform (AEP) Web SDK to ingest data. I have followed all the steps outlined in the tutorials, but I’m running into an issue during testing.

Here’s what I did:

1. I copied the JavaScript library from Data Collection → Environments → Development.
2. I included this JavaScript in a simple HTML page on my local PC.
3. When I load the page and open the debugger, I see an error saying: Web SDK not found.

Questions:

1. Is it mandatory to move this implementation to a cloud-hosted page for it to work? Does the Web SDK not support local testing?
2. During tag creation, does the Domain Setup field need to match the domain of the page where I’m testing? Could this mismatch be the reason for the "Web SDK not found"?

For reference, these are the steps I have completed:

1. Implement Adobe Experience Cloud with Web SDK tutorial
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/overview
2. Create an XDM schema for web data
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/initial-configuration/co...
3. Configure an identity namespace
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/initial-configuration/co...
4. Configure a datastream
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/initial-configuration/co...
5. Install Adobe Experience Platform Web SDK tag extension
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/tags-configuration/insta...
6. Create data elements
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/tags-configuration/creat...
7. Create identities
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/tags-configuration/creat...
8. Create tag rules
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/tags-configuration/creat...
9. Validate Web SDK implementations with Experience Platform Debugger
   https://experienceleague.adobe.com/en/docs/platform-learn/implement-web-sdk/tags-configuration/valid...

Any insights or suggestions would be greatly appreciated!

Thanks in advance!

Hi @lnl669 

first of all, you should be able to run the Web SDK on your local environment.

Can you confirm the following

• you have set up a Datastream in the Data Collection > Datastreams configuration
  
• you have the Web SDK extension installed in Adobe Launch, referring to your datastream configured above (Extensions > Installed)
  
• you have a Development library in Adobe Launch that has the Web SDK included (Publishing Flow > <your library>)
  

Once you have built your library, you should also be able to run this in your console

Hi @bjoern__koth , 

Thank you so much for this complete description.

I believe I did all the steps. I will cross-check and test again.

Hi @lnl669 
you're welcome! I just double-checked and cannot find any occurrence of "Web SDK not found" in the launch code.
Is that maybe some error message from your end?

Hello @bjoern__koth , 

I did the cross check please find this screenshot: 

I have done the test which you suggested, according to this file is there but in debugger it is showing web SDK not found.

I would like to know if I am missing thing.

Looks good. Your request payload is in the "events" section.

To be honest, using the debugger is extremely annoying, and I would recommend using one of the following extensions

• Omnibug: https://omnibug.io/ - has its own tab in the developer tools
• Universal Adobe Debugger: https://chromewebstore.google.com/detail/universal-adobe-debugger/ehadnibhemgjphdjgkallndphbghlpkn  - prints in the console

Both highly recommended!

@bjoern__koth  Thank you again!

No problem,

let me know if you have more questions

Chrome won't let you set cookies when you open a file locally with the file protocol. So, the cookie setting parts of Web SDK won't work and you might experience anomalies related to this when playing around with local files. Do you also see this error in the console?:

That's why we provide the Luma website for you to use while going through that tutorial--so you have a hosted website you can point to your own tags property. I produced that tutorial and it always makes me happy to see people using it. Please let me know if you have any feedback.
