Error: NoCredentialProviders

[llamafilm]

Hello. I've just downloaded goofys version 0.24.0-45b8d78375af1b24604439d2e60c567654bcdf88.
I'm running in EC2 with IAM instance profile but I'm getting this error when trying to mount:

s3.ERROR code=NoCredentialProviders msg=no valid providers in chain. Deprecated.#012#011For verbose messaging see aws.Config.CredentialsChainVerboseErrors, err=<nil>
main.ERROR Unable to access 'mybucketname': NoCredentialProviders: no valid providers in chain. Deprecated.#012#011For verbose messaging see aws.Config.CredentialsChainVerboseErrors
main.FATAL Mounting file system: Mount: initialization failed

The command I ran is ./goofys --region us-west-2 mybucketname /mnt/goofys/

I do not have a credentials file, and the aws cli works automatically using the instance role, e.g. aws s3 ls s3://mybucketname.

1. Try putting the aws credential file in /root/.aws or

2. The contents of the aws credentials file
   aws_access_key_id
   Check if it is aws_secret_access_key or

I solved it through number 1.

Same issue here. How is this possible to not being able to use the IAM instance profile? It was something deprecated, because we're using Goofys for a long time and this was supported before

I'm closing my own issue as a duplicate of #671.
