Rank 2: Process
Last day I deployed a function to my selfhosted Appwrite and its working fine when I execute it from console.
It even worked fine when I execute a GET request from my Flutter Windows App.
But It is showing following error when a POST request executed from Flutter App:
Plain text
File "/usr/local/server/src/server.py", line 210, in handler return await action(request) File "/usr/local/server/src/server.py", line 131, in action context.req.body = request.get_json(force=True, silent=False) File "/usr/local/server/src/function/runtime-env/lib/python3.9/site-packages/werkzeug/wrappers/request.py", line 623, in get_json rv = self.on_json_loading_failed(e) File "/usr/local/server/src/function/runtime-env/lib/python3.9/site-packages/flask/wrappers.py", line 131, in on_json_loading_failed raise BadRequest()werkzeug.exceptions.BadRequest: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.```
My Flutter Code:
```Execution result = await _functions.createExecution( functionId: AppwriteCredentials.hookGeneratorFunctionId, body: "{'user_message': $userInputText}", // optional method: ExecutionMethod.pOST, // optional headers: {"Content-Type": "application/json"}, // optional );```Summary
Issue with POST request from Flutter app to self-hosted Appwrite server. The provided JSON body format is invalid due to the use of single quotes. POST method is case-sensitive, but not the root cause of the problem. The error seems related to decoding JSON response on the server side. The Flutter code should use double quotes for JSON keys and values.
