Offline even with `--useDocker` tries to use lambci/lambda:haskell which doesn't exist

[danwdart]

Tried to use provided as runtime but I just get:

offline: [502] {"errorType":"exitError","errorMessage":"RequestId: 2cf06505-d533-17c1-57a0-edde6a345edc Error: Couldn't find valid bootstrap(s): [/var/task/bootstrap /opt/bootstrap]"}

Any ideas?

[koterpillar]

Can you please share your serverless.yml? This is being tested in the integration tests (https://github.com/seek-oss/serverless-haskell/blob/master/integration-test/skeleton/serverless.yml, https://github.com/seek-oss/serverless-haskell/blob/master/integration-test/run.sh#L162-L172).

@danwdart I'm getting this same error while trying to get serverless-offline to work. I'm testing the route in the browser by visiting http://localhost:3000/dev/value. The function works when I use sls invoke local -f get-value

Error

@koterpillar If you have a minute can you chime in on what I might be doing wrong?

[koterpillar]

I am able to use both local invocation and sls-offline in the above repository. Here's what I've done after cloning:

[seanhess]

Well, it's working for me now too. I have no idea what changed. Thank you for your help.

I didn't open this issue, but I was getting the exact same error as the OP earlier. You may want to consider closing.

[koterpillar]

If you find a way to reproduce it (from a clean checkout), please open a new issue.

[danwdart]

I do get this now but only when I specifically use runtime: provided on purpose.

[koterpillar]

The plugin manages the runtime and will not consider any runtime: provided functions as Haskell.

[danwdart]

Yep - just for those who came across this, that's what they need to know.
