Some workflow actions may accept a JSON object to update data. You need to ensure that provided JSON object is a valid otherwise the workflow will run into errors.
We recommend using the following tools to validate JSON object before submitting workflow:
The most common issue is having trailing commas in JSON object.
// Invalid
{
"name": "John Doe",
"age": 25,
}
// Valid
{
"name": "John Doe",
"age": 25
}
