May be Telegraph API does not support webp currently. 

 I downloaded your image and tried to upload through my site. It succeed.

See [this comment](https://github.com/cf-pages/Telegraph-Image/issues/14#issuecomment-1978085558). Issue could be closed.

Same issues. I use it this way: ```python class PythonBridge(IPythonBridge): def testFunc(self): print("running!!!!!") PythonUtils.setResult("result!!!!") ``` 🤣🤣🤣

Have to using pure-JS to implement it? How about WebAssembly? It can also be cross-platform and has good performance.

When this error occurs, you can use Google ADB to try to see if similar errors will occur.
