ERROR: LoadError: ArgumentError: ssl_unsafe_read requires isreadable(::SSLContext)

[sunayana]

I get the following error message, while trying to write quite a few files to an s3 bucket. Could it be related to AWS S3 throttling or could it be something else?

ERROR: LoadError: ArgumentError: `ssl_unsafe_read` requires `isreadable(::SSLContext)`

Which version of this package are you using? Could you output ] st?

[sunayana]

Which version of this package are you using? Could you output ] st?

I am using this one:
[1c724243] AWSS3 v0.10.0

[mattBrzezinski]

Can you post the version of MbedTLS and HTTP as well?

[sunayana]

Can you post the version of MbedTLS and HTTP as well?

MbedTLS v1.1.3
HTTP v0.9.17

[mattBrzezinski]

And what's the version of AWS.jl? You should try to upgrade to HTTP@1 and see if it replicates.

[sunayana]

AWS v1.75.1. Ok I try to see by upgrading.

[sunayana]

Thanks a lot it works now after upgrading to HTTP 1.2.1

[mattBrzezinski]

Perfect! I'll close this issue but if it crops up again feel free to reopen it.
