Hello to all, I’m quite new with Roboflow and I need a small help form the community I trained a public model to detect my cats: [gigio-and-astra Instance Segmentation Dataset and Pre-Trained Model by Home4Me](https://universe.roboflow.com/home4me/gigio-and-astra) I installed the Inference server on my RaspberryPi 4, and started the docker container. All rights here. But when I try to inference an image using the Url [http://pollicino:9001/gigio-and-astra/2](http://pollicino:9001/gigio-and-astra/2), I receive an error telling me: ```javascript { error: { error: { message: 'No trained model was found for this model version.', type: 'GraphMethodException', hint: 'You must train a model on this version with Roboflow Train before you can use inference.', e: [Array] } } } ``` Here my (dummy) js code: ```javascript require("dotenv").config(); const sharp = require("sharp"); const axios = require("axios"); const fs = require("fs"); async function test() { const resizedImageBuf = await sharp("./assets/IMG_2534.JPG") .rotate() .resize(500) .jpeg({ mozjpeg: true }) .toBuffer(); var image = `data:image/png;base64,${resizedImageBuf.toString("base64")}`; axios({ method: "POST", url: `${process.env.HOSTED_API}`, params: { api_key: `${process.env.API_KEY}`, }, data: image, headers: { "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8", }, }) .then(function (response) { console.log(response.data); }) .catch(function (error) { console.log(error.message); }); } test(); ``` Thanks for any help! ---

I tried also the python code: ```python rf = Roboflow(api_key="xx") project = rf.workspace("home4me").project("gigio-and-astra") model = project.version(2, local="http://localhost:9001").model prediction = model.predict("IMG_2534.JPG", confidence=40) ``` but in this case the docker container raises an error: ```auto TypeError: req.body.replace is not a function at transformImageBody (/inference-server/server/index.js:323:26) at Layer.handle [as handle_request] (/inference-server/server/node_modules/express/lib/router/layer.js:95:5) at next (/inference-server/server/node_modules/express/lib/router/route.js:144:13) at Route.dispatch (/inference-server/server/node_modules/express/lib/router/route.js:114:3) at Layer.handle [as handle_request] (/inference-server/server/node_modules/express/lib/router/layer.js:95:5) at /inference-server/server/node_modules/express/lib/router/index.js:284:15 at param (/inference-server/server/node_modules/express/lib/router/index.js:365:14) at param (/inference-server/server/node_modules/express/lib/router/index.js:376:14) at param (/inference-server/server/node_modules/express/lib/router/index.js:376:14) at Function.process_params (/inference-server/server/node_modules/express/lib/router/index.js:421:3) ``` ---

Hi, did you resolve this issue? I’m getting the same error now on a model I trained in a Colab Notebook and deployed back to Roboflow. The deployed model is available on my page but when I try to use it in my web app, I get this error: ```auto { "error": { "message": "No trained model was found for this model version.", "type": "GraphMethodException", "hint": "You must train a model on this version with Roboflow Train before you can use inference.", "e": [ "Could not parse size from model.json" ] } } ``` ---

Hi @MainBearing, are you also using the inference server docker? ---

Hi @stellashphere, no I’m just pulling it directly into a web page on my local test rig for now. I retrained the model on a new version and the issue is now resolved. No idea what went wrong with the previous version. ---
