Accessing Move Object Bags with SUI SDK
I am attempting to retrieve an object_bag
using the SUI SDK. When I used the getObject
function, it returned an error stating that the object does not exist. Could someone confirm if I need to utilize the getDynamicFieldObject
function instead? If so, what should I specify for the name parameter in order to successfully fetch the object_bag
?

2To access an object_bag
using the Sui SDK, you can follow these steps:
- Call
suix_getDynamicFields
: Use thesuix_getDynamicFields
function from the RPC API or find a similar function in the TypeScript (TS) SDK. This function returns a structure with a data field, which is an array ofDynamicFieldInfo
objects, specific to the object ID you pass in. - Iterate Through the
DynamicFieldInfo
Array: For each element in theDynamicFieldInfo
array, examine the type field. If the type field has a value ofDynamicObject
, you can extract the name field from theDynamicFieldInfo
object. This name value corresponds to the field containing theobject_bag
. - Use
getDynamicFieldObject
: Utilize thegetDynamicFieldObject
function, passing the extracted name as a parameter. This function allows you to retrieve theobject_bag
from the specified field. Please note that while I don't have the explicit TypeScript code, you can easily check the TypeScript source code to understand the exact function names, parameters, and usage within the Sui SDK. By following these steps, you can effectively access theobject_bag
using the Sui SDK. If you encounter any specific issues or have further questions, feel free to ask for additional assistance.
The getObject
function is used to retrieve an object by its ID. If the object does not exist or the ID is incorrect, it will return an error.
On the other hand, the getDynamicFieldObject
function is used to retrieve dynamic field object information for a specified object docs.zan.top.
If the object you're trying to retrieve is an object_bag
and it has dynamic fields, you might need to use the getDynamicFieldObject
function. The name parameter should be the name of the dynamic field you want to retrieve.
Here's a basic example of how you might use getDynamicFieldObject
:
et dynamicFieldName = 'yourDynamicFieldName';
let objectId = 'yourObjectId';
suiSDK.getDynamicFieldObject(objectId, dynamicFieldName)
.then(dynamicFieldObject => {
console.log(dynamicFieldObject);
})
.catch(error => {
console.error('Error retrieving dynamic field object:', error);
});
In this example, replace yourDynamicFieldName
with the name of the dynamic field you want to retrieve, and replace yourObjectId
with the ID of the object you're trying to retrieve.
However, if the object does not have any dynamic fields, or if the object does not exist, you will still encounter an error. In that case, you should double-check the object ID and make sure the object has been created before you try to retrieve it
