Hi all,

I've been running sessions on Prolific for months, but I'm now making the switch over to mturk. I've followed all the steps in the documentation for running on mturk, but when I go to post the HIT from the oTree admin page, I get errors.

When I select the 'Use MTurk Sandbox' option, the error reads: 

MTurkError({'__type': 'RequestError', 'Message': 'This user is not authorized to perform the requested operation.                                     (1705687446820 s)', 'TurkErrorCode': 'AWS.MechanicalTurk.PermissionDenied'})

and when I deselect the sandbox option, the error reads: 

MTurkError({'__type': 'RequestError', 'Message': 'This account has been suspended. (1705687489337)', 'TurkErrorCode': 'AWS.MechanicalTurk.PermissionDenied'})


I haven't found any discussion on any of the forums about these specific errors, so I'm hoping someone here has some ideas on a potential solution. Thanks!

Update:

These errors were due to a mismatch in access keys between my AWS account and Heroku. After fixing, new error reads: 

MTurkError({'__type': 'RequestError', 'Message': 'This Requester has insufficient funds in their account to complete this transaction. Please visit https://requester.mturk.com/prepayments/new to purchase Prepaid HITs (1706304893161)','TurkErrorCode': 'AWS.MechanicalTurk.InsufficientFunds'})

I've read elsewhere that this error is due to a default spending limit of $0.02 on MTurk. Apparently, customer support is required to raise this limit. I've reached out to support and given them my preferred spending limit - I'll update when I get a response.
