@Matte Fall - I have not fully, but I stumbled on a potential solution working with another project when processing images. I will try it out tomorrow and update

Hi, I found the solution now. @Matte Fall the n8n nodes for Slack is missing a Download feature so you need to use the regular HTTP call node. I have attached a print screen. Steps: 1. Trigger Slack node 2. Use the Get File Slack Node and get the file content (I used a switch before to steer it towards this branch if there is a audio file in the message) 3. Use the HTTP API call node and set it up as below. Using your credentials for the Slack connection and the private_download_url from the Get File Node. 4. And the Retrieve formate File - data. Thats it, after that you can use the OpenAi Whisper Node to transcribe the audio. All the best, Jens

Hi Adrien, I also got error in the similar way. As the field you are trying to add values into, is a field that is connected to another table, the API documentation states that the values must be within [ ]. I simply instructed my agent in the description of the fromAi function with the following. (Below is an example when adding a new user to our CRM in AirTable and we want to connect the user to an existing company.) "The id for the company which you want to connect the individual to. The ID needs to be within [] i.e ["record_id"] " Hope this helps you, All the best, Jens
