[BUG] Cannot create WebActivity headers

[chinarosesz]

Library name and version

Azure.ResourceManager.DataFactory v1.0.0-beta.4

Describe the bug

I'm having a lot of trouble creating a web activity headers. I've tried using literal string, secure string, and expression. And none of this worked for the basic scenario such as setting a basic key/value pair.

The previous SDK worked because the headers takes in a dictionary, but the new SDK takes in a DataFactoryElement.

Expected behavior

Generated key value pairs for headers

Actual behavior

Generated value of 0, 1, 2, 3, and each character from the literal string as single item.

Reproduction Steps

// Create pipeline web activity
DataFactoryElement uri = $"@concat('https://{functionAppName}.azurewebsites.net/api/SyncPermissionsFunction?organization={org.Url}&code=',pipeline().parameters.functionkey)";
WebActivity webActivity = new WebActivity("SyncPermissionsFunction", WebActivityMethod.Get, uri);

// This line does not work.
webActivity.Headers = DataFactoryElement.FromLiteral("foo");

Environment

No response

Thank you for reporting the issue. Could you please share the name of the SDK you are trying to use?

[chinarosesz]

Yes. This is the package I am using.

    <PackageReference Include="Azure.ResourceManager.DataFactory" Version="1.0.0-beta.4" />

What's the error you see here? From my perspective, you are using expression, so you can try something like:

var uri = DataFactoryElement<string>.FromExpression($"@concat($"@concat('https://{functionAppName}.azurewebsites.net/api/SyncPermissionsFunction?organization={org.Url}&code=',pipeline().parameters.functionkey)");
var webActivity = new WebActivity("SyncPermissionsFunction", WebActivityMethod.Get, uri);

I’m trying to pass in the headers. And the headers should be treated like an object or a dictionary. As of now it only takes in a string, and there is no way for me to construct headers if it is of type string. I have tried the whole day to construct the headers from the SDK and have no luck. Can you try on your side to construct a webactivity with headers?

I'm facing same problem but from other side, I want to run GetDataFactoryPipelines method on DataFactoryResource class and it is throwing exception System.InvalidCastException: 'Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'System.String'.'

Turns out deserializing code wants to read String, but JSON returned from API has "headers": {} hence exception...

This is weird, linked code is different than one I'm debugging:

Notice that debugged code is not decompiled, but came from source server...
