who to insert array in body part of post request I am getting 500 error. I verified with post man that is due to removing square bracket.

—body part is—  
{

“action”: [  
“sa.pia.is.w”

]  
}

------in my code what I am written is------  
${body} Create Dictionary action=sa.pia.is.w

What you’re sending in Postman is different from what you send using RF. What you can try:

```python
${actions_list}= Create List sa.pia.is.w
${body}= Create Dictionary action=${actions_list}

```

Also note that data validation on the endpoint is lacking if you receive a 500 response on invalid data (in your case, a string instead of a list of strings). A typical response would be 422 in such a case.
