In my project, I am recording audio using ‘Audio Recorder and Visualizer’ plugin. Then I upload the recorded audio, and now want to send that File to an external self-hosted API where ‘sound’ is the parameter name. During API setup, the “initialize call” works fine, with response coming in ‘preview’ section. But when I trigger it while using my app, it gives me error.
It gives me this error: “API Connector error: the parameter sound is not a valid file bubble.io”
Following are the api setup, workflow, step-by-step and error images. Please help.
