I'm trying to build yesod according to the docs on docker:
# Dockerfile
FROM ubuntu:22.04
RUN apt-get update
RUN apt-get install curl -y
RUN curl -sSL https://get.haskellstack.org/ | sh
RUN stack new my-project yesodweb/sqlite
RUN cd my-project && stack install yesod-bin --install-ghc
RUN cd my-project && stack build
I get until the next to last step, but then fail:
> docker build --tag host_yesod --file Dockerfile .
=> [1/7] FROM docker.io/library/ubuntu:22.04@sha256:6042500cf4b44b 0.0s
=> CACHED [2/7] RUN apt-get update 0.0s

=> CACHED [6/7] RUN cd my-project && stack install yesod-bin --install-ghc
=> ERROR [7/7] RUN cd my-project && stack build 100.7s
Here is the error message:
100.6 Error: [S-7282]
100.6 Stack failed to execute the build plan.
100.6
100.6 While executing the build plan, Stack encountered the error:

100.6 While building package language-javascript-0.7.1.0 (scroll up to its section to see the
100.6 error) using:

100.6 Process exited with code: ExitFailure 1
Any ideas how can I fix this?
EDIT
The line you're looking for is
92.67 language-javascript
> happy: src/Language/JavaScript/Parser/Grammar7.y:
hGetContents: invalid argument (invalid byte sequence)
Googling "docker" hGetContents: invalid argument (invalid byte sequence) tells us that this means the source code file is not UTF-8 and leads to this StackOverflow answer. So try appending the line en_US.UTF-8 UTF-8 to the /etc/locale.gen file in your docker image.
