Cannot create documents via the Extension Data APIs (404)

[epignosisx]

Hi folks. I'm trying to create a document using the Extensions Data API but I keep getting a 404 with the following response:

{"Message":"No HTTP resource was found that matches the request URI 'https://extmgmt.dev.azure.com/_apis/ExtensionManagement/InstalledExtensions/merge-a-bot/Data/Scopes/Default/Current/Collections/MergePolicies-Automerge/Documents'."}

Here is how my request looks like

{"strategy":"SpecificSourceAndTargetPolicy","repo":"Automerge","source":"asdf","target":"asdf"}

Here is the outcome in the Network Tab:

This is how my code looks like:

export async function createPolicy(strategy: string, repo: string, source: string, target: string): Promise<void> {
    var context = SDK.getExtensionContext();
    var token = await SDK.getAccessToken();
    var dataService = await SDK.getService<IExtensionDataService>(CommonServiceIds.ExtensionDataService);
    var mng = await dataService.getExtensionDataManager(context.extensionId, token);
    var doc = await mng.createDocument("MergePolicies-" + repo, { strategy: strategy, repo: repo, source: source, target: target });
    console.log(doc);
}

and I'm making sure to initialize the SDK on page startup:

SDK.init().then(() => {
    ReactDOM.render(<App />, document.getElementById("root"));
})

Finally, I've been following this guide based on the old VSS and adapting it to the new SDK/API packages:

Really appreciate your help here, I've run out of troubleshooting ideas.

Figured out the problem. The extension id is actually a concatenation of publisher id and extension id:

export async function createPolicy(strategy: string, repo: string, source: string, target: string): Promise<void> {
    var context = SDK.getExtensionContext();
    var token = await SDK.getAccessToken();
    var dataService = await SDK.getService<IExtensionDataService>(CommonServiceIds.ExtensionDataService);
    //var mng = await dataService.getExtensionDataManager(context.extensionId, token); <-- replaced by line below
    var mng = await dataService.getExtensionDataManager(context.extensionId + "." + context.extensionId, token);
    var doc = await mng.createDocument("MergePolicies-" + repo, { strategy: strategy, repo: repo, source: source, target: target });
    console.log(doc);
}

Couple of years later stumble on the same problem! Thanks for finding this @epignosisx

Heads up - extensionId is repeated twice so when your publisherId and extensionId are different it'll still be broken.

var mng = await dataService.getExtensionDataManager(context.publisherId + "." + context.extensionId, token);
