### **Environment:**

Your OpenProject Version: 11.4.0 (BIM Edition, Begin of the insertionself-hosted)End of the insertion Begin of the deletion self-hosted) End of the deletion

Operating System / Browser / OpenProject language: Ubuntu Server 20.04 LTS / Google Chrome 94.0.4606.71 / Russian

### **Logs**

Attached.

Begin of the insertionThe important bits are 

```text
Something went wrong: Error: Cannot create a string longer than 0x1fffffe8 characters
at Buffer.toString (buffer.js:778:17)
at JSON.parse (<anonymous>)
at convert (/home/wieland/.nodenv/versions/14.17.0/lib/node_modules/@xeokit/xeokit-gltf-to-xkt/gltf2xkt.js:65:23)
at async main (/home/wieland/.nodenv/versions/14.17.0/lib/node_modules/@xeokit/xeokit-gltf-to-xkt/gltf2xkt.js:56:24) {
code: 'ERR_STRING_TOO_LONG'
}
```

0x1fffffe8 (which is a hexadecimal number) is 536.870.888 as a decimal number, which makes sense as the current string size limit in Node.js is about 1GB.

End of the insertion ### **Steps to reproduce:**

1. Go to BCF -&gt; IFC models
2. Click on button &quot;+ IFC model&quot;
3. Select a BIG file (&gt;190 MB) contains IFC4 model, click on button &quot;Create&quot;

### **Actual Behavior**

The file was uploaded successfully, processing status of that file is &quot;In progress&quot;. Processing started and was never completed. The log file contains records about processing error on stage gltf2xkt. I think the problem is the string length limit in Node.js included in disribution. The error occurs on Begin of the insertion[lineEnd of the insertion Begin of the deletion lineEnd of the deletion 65 in gltf2xkt.js Begin of the insertionfile](https://github.com/xeokit/xeokit-gltf-to-xkt/blob/f21ef0944003f64640226646156e327de7d460c1/gltf2xkt.js#L67):End of the insertion Begin of the deletion file:End of the deletion

Begin of the insertion`constEnd of the insertion Begin of the deletion constEnd of the deletion gltf = Begin of the insertionJSON.parse(gltfContent);`End of the insertion Begin of the deletion JSON.parse(gltfContent);End of the deletion

Could you change this handling to get rid of this error?

### **Expected Behavior**

Processing completed successfully.
