Unable to import multiple tasks via URL

[wish2023]

Hi, I'm working on importing multiple tasks to a project via URL:

url1 = "http://localhost:8081/synthetics5.png"
url2 = "http://localhost:8081/synthetics6.png"
data1 = {"url": url2}
data2 = [{"url": url1}, {"url": url2}]
r = ls.make_request('POST', f'/api/projects/{project_id}/import', data=data2)
print(r.status_code)

I can successfully import using data1 but get the following error using data2 :

Traceback (most recent call last):

Hi @wish2023 Please wrap your data in json.dumps:

r = ls.make_request('POST', f'/api/projects/{project_id}/import', data= json.dumps(data2))

and add extra headers to your LS client:

headers = {'Content-type': 'application/json'}
ls = client.Client(url='http://127.0.0.1:8000/', extra_headers=headers)
