Were you able to resolve this error?

I am receiving the same phx_template_not_found error.

Thank you

I should also mention that my code is nearly identical and I also have created the template in the appropriate directory.

I honestly can’t remember exactly. I think it was some broken reference to a .json in book.view.ex

General rule: if you think it’s Phoenix’s fault it’s probably actually your fault.

Hahaha, thanks for the reply. I have a feeling you're right and I'm not parsing the json correctly (I want to render the output from another API and I have a feeling that's the issue).

Cheers,
Thomas
