First import fails, second import succeeds on julia 1.4.2

[bb4242]

Hi! I noticed that on julia 1.4.2, the first time I attempt to import AWSS3, it fails, but the second time succeeds:

julia> import AWSS3
ERROR: InitError: MethodError: Cannot `convert` an object of type Type{AWSS3.S3Path} to an object of type DataType
Closest candidates are:

julia> import AWSS3

Do you have any idea what might cause this? I did notice that the import succeeds the first time when using julia 1.6.0, but I'm unfortunately stuck on 1.4.2 due to unrelated factors for the moment.

I've attempted to reproduce this with Julia 1 and 1.3 (as I don't have 1.4 installed), and was unable to. Do you run into this same issue when doing the following?

using AWSS3

Thanks @mattBrzezinski! Yes, I do see the same issue when doing using AWSS3 instead of import AWSS3. A couple of other data points:

Still using julia 1.4.2, I tried installing AWSS3 version 0.7.7 instead of 0.8.3. After doing that, here are the packages I have installed:

  "SymbolServer"          => v"5.1.1"

Interestingly, using that version, using AWSS3 works fine the first time. But I get a different error when running this little test script to download a file from S3:

using AWS
using AWSS3
c = global_aws_config(; region="us-west-2")
r = s3_get(c, <my bucket>, <my key>)

[email protected] uses AWSCore.jl in the backend, while 0.8+ uses AWS.jl. The stack overflow error is probably because you're passing in an AWS.AWSConfig instead of an AWSCore.AWSConfig object.

Do you have any other versions of Julia that you use? I can setup 1.4 and see if I can reproduce later on this week.

Ah, thanks! I was able to successfully run my script when using AWSCore.AWSConfig on [email protected].

I deleted my ~/.julia directory, installed julia 1.3.1 and 1.5.4, and tested those against AWSS3 (for fun, I tried against both 0.7.7 and 0.8.3. using AWSS3 works fine for both julia versions. Here's a summary table of everything I've tested so far:

	julia 1.3.1	julia 1.4.2	julia 1.5.4	julia 1.6.0
AWSS3 0.7.7	works	works	works	works
AWSS3 0.8.3	works	fails	works	works

Haha so apparently this problem is very specific to julia 1.4.2 and AWSS3 0.8.3!

Closing as this package is now at 0.11 and requires Julia 1.6 at a minimum.
