Hi, @dtMndas. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported a ConnectError in the langgenius/dify_extractor plugin due to SSL certificate verification failure with a self-signed certificate.
  • The issue occurs during workflow execution on Dify 1.9.1 and plugin version 0.05 in a self-hosted Docker environment.
  • The error message suggests contacting the plugin author for assistance.
  • No further updates or comments have been provided since the initial report.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • If I do not hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!

If you are having this issue, the problem happends due to the dify_plugin lib:

    @property
    def blob(self) -> bytes:
        """
        Get the file content as a bytes object.

        If the file content is not loaded yet, it will be loaded from the URL and stored in the `_blob` attribute.

        Raises:
            ValueError: If the URL uses an unsupported protocol (e.g., missing 'http://' or 'https://'),
                        suggesting configuration of the FILES_URL environment variable.
            httpx.HTTPStatusError: If the request to fetch the file fails.
        """
        if self._blob is None:
            try:
                response = httpx.get(self.url, verify=False)  # <<<<<< HERE set verify = False to avoid ssl verification, or add cert file
                response.raise_for_status()
                self._blob = response.content
            except httpx.UnsupportedProtocol as e:
                raise ValueError(
                    f"Invalid file URL '{self.url}': {e}. "
                    "Ensure the `FILES_URL` environment variable is set in your .env file"
                ) from e

        assert self._blob is not None
        return self._blob
