Both Quickstart samples fail

[aillusions]

Hi

I'e tried 2 sample apps from this guide https://haystack.deepset.ai/overview/quick-start and none of them have worked ..

Env:

python --version
  Python 3.12.6

pip show haystack-ai
   Name: haystack-ai
   Version: 2.5.1

first of them throws error:

haystack.core.errors.PipelineUnmarshalError: Error unmarshalling pipeline: Couldn't deserialize component 'converter' of class 'HTMLToDocument' with the following data: {'init_parameters': {'extractor_type': 'DefaultExtractor'}, 'type': 'haystack.components.converters.html.HTMLToDocument'}. Possible reasons include malformed serialized data, mismatch between the serialized component and the loaded one (due to a breaking change, see https://github.com/deepset-ai/haystack/releases), etc.

second

ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)

How to troubleshoot those?

thx

Thanks for the report, I created issue #8391 to track this.
We need to update the predefined Pipeline template to fix these issues. For the time being I would suggest using the code from the "Corresponding Pipeline" tab.

Fixed in #8401 and deepset-ai/haystack-home#371.
The fix will be released in 2.6.0.
