BadArgument error when building attendees array for “Find meeting times(V2)” / availability flow

Hello everyone,

Could someone please help me with an issue I’m facing in Power Automate?

I’m creating a flow to check common availability for multiple attendees. To build the attendees array, I’m using the following JSON

{
  "type": "required",
  "emailAddress": {
    "name": "@{outputs('Obter_perfil_do_usuário_(V2)')?['body/mailNickname']}",
    "address": "@{trim(items('Aplicar_a_cada'))}"
  }
}

However, when I run the flow, I receive a BadArgument error related to the parameters being passed.

It seems the attendees object is not being accepted in the expected format, but I’m not sure what needs to be adjusted.

Could anyone help me understand the correct structure for the attendees array ?

Any guidance or examples would be greatly appreciated.

Thank you!

Hi

Can please show a screenshot of your Find meeting times (V2) action step? Are you passing the JSON in the Required attendees field?

I guess the format is wrong. It needs to be a String and look like this:

Let me know if it worked!
