Hi @Anonymous

could you please also share a picture of your array variable you try to add?

It says that your JSON is not correct. Before running the "start and wait for an approval" you can add an "Compose" and see the results first. It should be in this structure:

[ { "name": <name 1>, "content": <content1> } ]

or with multiple attachments:

[ { "name": <name 1>, "content": <content 1> }, { "name": <name 2>, "content": <content 2> } ]

Does this help you? Otherwise please give me some more information.

Best regards
Marvin

Hi @Anonymous

within your 'append to array variable' it looks like you are missing some double quotes (") around the 'display name' dynamic value, otherwise it's not interpreted correctly. Also, the "ContentBytes" might not work, please try "content" instead. Around the body dynamic value you don't need any quotes, because you have an object you need to pass in there. This should be the syntex:

{ "name": "<display name dynamic content>", "content": <body dynamic content> }

Does this help you? Otherwise please give me some more information.

Hi @Anonymous

please check the approval action where you put in the array.

The "Add new item" below your array isn't right it shouldn't display, when you want to enter an array, you need to click on the "switch input icon" (in red square) and then put in your array. So please first delete the array variable from this field, click on the icon so that it looks like this:

And then you can put in your array again. Please try then try again. If you have problems, you can also try to delete and readd the approvals action.

Does this help you? Otherwise please give me some more information.

Best regards
Marvin
