Where is APPWRITE_FUNCTION_EVENT_DATA for dart language in function

I am writing the function in dart language. I want to get the data when the document is created. However I don’t know how can I get the JSON data from APPWRITE_FUNCTION_EVENT_DATA.

Anyone use Dart language to advise me.

Thanks

TL;DR

The user is asking for help with the `APPWRITE_FUNCTION_EVENT_DATA` in Dart language. They have checked their environment variables and `envVars['APPWRITE_FUNCTION_EVENT_DATA']` is null. They are trying to access the data in `APPWRITE_FUNCTION_EVENT_DATA` but getting a null error. The error seems to be occurring when the event is triggered. They are using a cloud platform. Possible solution: - Make sure that the `APPWRITE_FUNCTION_EVENT_DATA` environment variable is properly set and accessible. - Print out the `envVars` variable to check if it contains any data. - Check if the

Do you not get the data from the response? Are you using cloud or self hosted? Also can you share your function code?

I used cloud platform.

Here is my code.

TypeScript

Map<String, String> envVars = Platform.environment;
final payload = jsonDecode(envVars['APPWRITE_FUNCTION_EVENT_DATA']!);

I got the error when the event is triggered. Here is the error message.

TypeScript

Null check operator used on a null value
#0      main (package:starter_template/main.dart:39)
#1      main.<anonymous closure>.<anonymous closure> (file:///usr/local/server/src/server.dart:115)
#2      _rootRun (dart:async/zone.dart:1399)

#7      handleRequest (package:shelf/shelf_io.dart:138)

If I remember, the event data is now get from context.req.body, if isn't try looking the req object

Have you checked your environment variable APPWRITE_FUNCTION_EVENT_DATA? Can you print out the envVars has data

I print context.req.body. It looks like not the json format.

The envVars['APPWRITE_FUNCTION_EVENT_DATA'] is null

TypeScript

context.req.body is {name: ghhh, phone: 25852588, email: yyg@bhg.bvg, gender: M, church: ghh, yearInHIM: 22, yearInBaptist: 2585, churchService: , yearInChurchChoir: , otherChoir: , yearInOtherChoir: , part: , musicTalent: , otherTalent: , $id: 0AAwOPZM8b25852588, $permissions: [read("user:658438032da8455c4141"), update("user:658438032da8455c4141"), delete("user:658438032da8455c4141")], $createdAt: 2023-12-21T13:33:11.792 00:00, $updatedAt: 2023-12-21T13:33:11.792 00:00, isEmail: false, $databaseId: default, $collectionId: applicationList}
envVars['APPWRITE_FUNCTION_EVENT_DATA'] is null

I meant print out all the environment variables envVars and check, it could be a typo issue

Yes. I print all for environment variables envVars. However I can’t find the key “APPWRITE_FUNCTION_EVENT_DATA”. Where is the event data?

TypeScript

APPWRITE_API_KEY
APPWRITE_FUNCTION_RUNTIME_NAME
HOSTNAME
HOME
OLDPWD
APPWRITE_FUNCTION_API_KEY
FROM_ADDRESS
TO_ADDRESS
EMAIL_SUBJECT
PATH
APPWRITE_FUNCTION_NAME
SENDGRID_API_KEY
INERNAL_EXECUTOR_HOSTNAME
OPEN_RUNTIMES_ENTRYPOINT
APPWRITE_FUNCTION_RUNTIME_VERSION
APPWRITE_FUNCTION_ENDPOINT
APPWRITE_FUNCTION_ID
DART_SDK
PWD
OPEN_RUNTIMES_HOSTNAME
APPWRITE_FUNCTION_DEPLOYMENT
APPWRITE_FUNCTION_PROJECT_ID
OPEN_RUNTIMES_SECRET

Since 1.4, they should be in context.req.body. And it should be decoded for you already (so it's a Map)
