KeyError: 'content-type' when using delete_rows

[qprotex]

Describe the bug Since March 6th, delete_rows has consistently generated the error KeyError: 'content-type'. Before, the script worked fine for months.

To Reproduce Steps to reproduce the behavior:

1. Create a smartsheet instance
2. Get a specific sheet
3. Call smart.Sheets.delete_rows inside a loop

smart = smartsheet.Smartsheet(access_token=xxx, max_retry_time=60)
sheet_id = xxx

chunk_interval=300
while True:
    sheet = smart.Sheets.get_sheet(sheet_id)
    rows_to_delete = [row.id for row in sheet.rows]
    if not rows_to_delete:
        break
    for x in range(0, len(rows_to_delete), chunk_interval):
        smart.Sheets.delete_rows(sheet.id, rows_to_delete[x:x + chunk_interval])

Expected behavior Rows should be deleted

Screenshots

Environment (please complete the following information):

• Windows 11
• Smartsheet Python SDK Version 3.0.2
• Python Version 3.11.7

I also get this error intermittently when calling Home.list_all_contents() and Sheets.get_sheet(). It seems to happen for no rhyme or reason, because the requests usually succeed, and I only get this error occasionally. I'm having this issue now, see below for an example.

To reproduce:

1. Initialize a Smartsheet object
2. Call Home.list_all_contents()

Expected behavior: I should receive a list of all the Smartsheet objects associated with my account
