Workflow API vague error messages (Internal error)

[Help_sq]

I am experiencing some strange occurrences with the workflows API, specifically, I am unable to POST a new workflow action most times I've tried, even when the payload is the exact same. I did first delete the created action via the DELETE endpoint before trying again with the exact same payload. I currently have one action created but here is the payload I am currently trying that keeps failing:

const definitionResponse = await axios.post(
            "https://api.hubapi.com/automationextensions/v1/definitions",
            {
                integrationAppId: <<redacted>>,
                extensionName: "Create a Charge",
                webhookUrl:
                    <<redacted>>,
                fieldMetadata: [
                    {
                        label: "Product Name",
                        key: "product_name",
                        fieldType: "TEXT",
                        values: [

                    },
                    {

@Teun , anything jump out to you here?

Hi @Help_sq ,

What kind of errors do you get when you try to POST this request? You should be able to get some detailed errors using Axios. Could you try to give us some logs?
