Question

enter image description here Each dependency is properly installed . The error is specific to the line :

const result = await summarizer.run(
        `Summarize the following text: ${event.data.value}`
      );

and the error is :

TypeError: Cannot read properties of undefined (reading 'step')
    at async V1InngestExecution.userFnToRun (src\inggest\functions.ts:28:21)
  26 |       });

  29 |         `Summarize the following text: ${event.data.value}`
  30 |       );

Please add code and errors as text (using code formatting), not images. Images are problematic for many reasons, including that they don't allow copy-pasting text for testing or searching. — Torge Rosendahl

I faced the same issue after upgrading to the latest version 3.44.5. I couldn't find significant update in the official docs to address whether or not anything changed drastically in the SDK. For the time being I rolled back to 3.44.2 which worked for me.

npm i [email protected]

Run this in the terminal, hopefully it would solve the issue for you and also gemini-1.5-flash and others from 1.5 series of models have been long depreciated by google may be go with something newer like gemini-2.5-flash.
