TensorFlow.js version:
"@tensorflow/tfjs": "^4.1.0"

I get this error message during prediction but the problem comes from the way the model was loaded. Indeed, when I load my model with tf.loadGraphModel and my model (.json + .bin) is on local or public server I have no problem.
when the model is loaded (without error message) from an external filesystem I get this problem. I'm sure that the .json has been loaded correctly and that it refers to the .bin weights.
Where I have a doubt is on the encoding or format of the .bin that are returned through the filesystem.

However when I consult the responses to the requests, it seems that the .bin is complete:

(locally with predictions that work)

(locally with predictions KO)

Please, Is there anything I missed?

(the filesystem extracts the data "application/octet-stream" and I return the buffer (data.Body) as it seems to be done when the model is served locally)

thank you in advance for your help
