Error: data was not an array when updating customfield and components Python


Here is my python code to create a ticket in Jira:

#Extract values from Excel sheet

Components = getCellValue(ws, 12, 2)
TestLevel = [getCellValue(ws, 14, 2)]

issue_dict = {
'components': {'FIELD': Components},
'customfield_10301': {'value': TestLevel}

new_issue = jira.create_issue(fields=issue_dict)

"errors":{"components":"data was not an array","TestLevel":"data was not an array"}


I am unable to figure out the reason behind this above error. 

Did anyone face such issue?

I found following worked with Python when updating the components:

issue.update(notify=False,update={"components": [{"add": {"name": str(NAME),}}],},)

Where NAME is the component name wisheds to be updated

Hello @santoshamoghavarsh.reddy ,

Welcome to the Atlassian Community.

I might not be the best person to answer this question but, reading the error message, it looks like you should pass an array of objects instead of a single value:


'customfield_10060': [{'value': 'Customer'}]


For further details on this, you may want to review below threads:
