@joshiewtf i believe vertex pdf needs to be on gs://

this is the comparable vertex example:

await chat.sendMessageStream([
  {
    text: 'Where is this candidate based?'
  },
  {
    fileData: {
      mimeType: 'application/pdf',
      fileUri: 'gs://resume.pdf'
    }
  }
]);

do you have http pdf files working with vertex ai today? would help to see a working code example @joshiewtf

Docs don't say anything here about it:

looking here - https://cloud.google.com/vertex-ai/generative-ai/docs/model-reference/inference#non-stream-multi-modality

it says the file uri is on google cloud storage

if you can share a working call with pdf, that would help @letmefocus
