SMS consent bulk operation always fails

[Eligijus_Lipski]

Hi,

I am trying to upload customers for SMS consent and am always getting a "Unexpected file structure - expected JSONL" error. 

The file I'm trying to upload has these conents: 

{"input": {"customerId":"gid://shopify/Customer/1223585300538","phone":"+995597957887","smsMarketingOptInLevel":"SINGLE_OPT_IN","marketingState":"SUBSCRIBED"}}

What might I be doing wrong ?

I don't suppose you ever worked this out did you?  I am getting the same thing
