Error - No JSON object could be decoded

[dhakim]

Hello,

I am facing an issue with form deployment. I have installed Kobo Toolbox on my own server around 6 months ago which was working fine but after the recent update, I am unable to deploy any form. I posted this question on the community forums and have read different topics on the same error but couldn't resolve this issue. I asked the similar question here https://community.kobotoolbox.org/t/error-unable-to-deploy-no-json-object-could-be-decoded/8888/8.

After some investigation in logs, I found below traceback in kobocat logs

Its seems like kobo toolbox is not able to connect with my S3 bucket using the credentials I provided but the same credentials I checked are working on aws cli.
