API Call Mapping to DataType not working

[cadufreeela]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When calling my methods that must be parsed to a custom datatype, the mapping is not done and the data Object is empty. It was working before and now it has stopped.

I created a different method and used the api call response to generate a mapping object that matches the data types, and did the correct mapping to the fields in my pages and the data is not updated when api call is executred.

I have a method /getAIPriceSettingsByLocation and used its response and created a new data object using the payload

{
"status": "Success",
"location": "AU",
"ai_price_settings": {
"image2video": {
"baseprice": 1,
"vid10seconds": 2
},
"text2video": {
"baseprice": 1,
"vid10seconds": 1
}
}
}

Once the data type object was created per the payload, I did the mapping in the API Call settings DataType (parse as data type=true) and selected the data type recently created. The mapping object was empty when I ran the api call from my on page load.

When I changed it to predefined Json Paths it worked

Expected Behavior

Correct mapping should be done

Steps to Reproduce

Create page
Create an api method call
Create a data type using the api call payload response
Map the api call response as data type and link to the new data type object
Add api call to onPageLoad
Inspect value of new Object in debug

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Visual documentation

Environment

- FlutterFlow version: 6.3.1
- Platform:MAcOs
- Browser name and version:
- Operating system and version affected: MacOS 15.6

Additional Information

This issue also affected other Get call that was perfectly working before, also the data type was created using the payload from the response.

Note: All data types matches the type expected: string>string, number>integer, etc

Hi there!
Sorry to hear you're running into this issue. I’ve tried to reproduce it on my end but haven’t had any luck so far. Please make sure that the structure of your DataType matches the structure of your API response.
Could you let me know which platform and operating system you’re using with FlutterFlow, as well as the version you’re currently on?
If you’re able to recreate the issue in a brand new blank project, that would really help speed things up on our side.
Please also send me the bug report code from that new project so I can take a closer look.
Thanks in advance!

Did you try using a payload structure that looks similar to mine?

For simpler payloads { "key":value...} it works, but for more nested ones it doesnt

{ "key1":value,1 "key"2: {"key2-1": value2-1,"key2-2":value2-2}}

Also the names in the payload matches the names in the datatype, both name and type

• FlutterFlow version: 6.3.1
• Platform:FF Desktop
• Browser name and version:
• Operating system and version affected: MacOS 15.6

Hi again!
Yes, I’ve tested it using a different nested data type, but I’m still unable to reproduce the error.
To continue investigating, could you please try reproducing the issue in a fresh, blank project? That would help us resolve your issue as quickly as possible.
Best regards

started the project in test mode. Value is 0 should be 132

As you can see in the image below, the appState mapped to the datatype which is mapped to the API Call response is not storing any values, however the API response is shown is json but mapping is not working. These are the scenarios I tried: 1. Another MacOS FF desktop (same latest version 6.3.1) 2. New blank project as stated above with dataType file created from json response payload 3. New dataTypeFile created manually with fields and type matching the expected response 4, New appstate created for each dataType (in scenario 2 and 3) 5. text field mapped to api call via "Add backend query to this widget" 6. text field mapped to api call via On Page Load (API call > update app state to api call response > json Body to Datatype) <----- THIS WORKED! All tries 1 to 5 didnt work, its failing to map fields when API call is set on "Add backend query to this widget" On Sat, 13 Sept 2025 at 08:28, Carlos Linares ***@***.***> wrote:

Hi again,

Thank you for providing more information. Before I escalate this issue further, I'd just like to ask one last thing: could you please show me the actual response from the API in your test project? I'm currently unable to test it myself using the default token.

This will help confirm whether the API response matches the field names and structure of your DataType 'datasys2' .

Looking forward to your response.
Best regards

[cadufreeela]

This is the response, however I need to mask some of the values however I will keep the type for them: { "status": "Success", "location": "AU", "preferences": { "payments_stripe": true, "maxChatTimeAllowance": 4, "visionAIAnalysis": true, "photoChatFeature": false, "forceDealsRushTimeLimits": false, "forceRushTimeLimits": false, "freePostAllowedFlag": true, "cloudVersionBuild": 132, "forceversiondownload": false, "promocodes": false, "videomaxlengthsec": 10, "suburbradiuslookup": 2, "forceCreditsPurchase": false, "KLING_AI_MAX_CONCURRENT": 3, "FREEELA_ASIA_URL": "https://xxx.cloudfunctions.net/app", "APIEndpoint": { "AU": { "TEXT2VIDEO": "https://xxx", "IMAGE2VIDEO": "https://xxx" } }, "AI_WH_ENDPOINT": "xxxx", "product_pricing": { "flow": { "currency": "AUD", "CPL": 1, "erpsku": "FLOW001", "taxcode": "GST_FLOW", "baseprice": 0.00 }, "rush": { "currency": "AUD", "ERPSKU": "RUSH001", "taxcode": "GST_RUSH", "baseprice": 1 }, "deal": { "currency": "AUD", "erpsku": "DEAL001", "taxcode": "GST_DEAL", "baseprice": 0.00 } } } }

Hi again!
Thank you for sending me this information. It seems that the structure of your data types doesn't exactly match the response you're receiving from your API call.

If you're still having trouble adapting your data types to match your API responses, feel free to reach out to support via the in-app chat. They can help you verify that your project is set up correctly.

Best regards!

[cadufreeela]

Actually on the email i sent you previous to the last one I tested a scenario where it worked doing the mapping on the On Page Load event
