My NestJS backend returns a pdf file. In local environment it works fine. My React code to handle the file:

const response = await axios.get(`leagues/${leagueId}/matches/${matchId}/reports/${reportType}`, {
  responseType: 'blob',
});

const blob = new Blob([response.data], { type: 'application/pdf' });

I open PDF and it displays properly.

However when I deploy my backend code to AWS Lambda it stops working even though response.data in my frontend app is exactly the same. I even opened both files in VSCode and they are exactly the same but first PDF displays properly and second one is just white blank.

I suspect that it does not return binary-type response. Is there any way to produce PDF blob from a non binary response?
