422 API Request Client Error from Shopify CLI in CI/CD Pipeline

[phv-ppuente]

I have been using the Shopify CLI in Github Actions to automatically deploy changes to a development theme for testing when a developer opens a pull request. It's been working great for months, but today all deployments started failing with the error message "[422] API request client error".

I've configured the following environment variables per Shopify's article (https://shopify.dev/docs/themes/tools/cli/ci-cd)

- SHOPIFY_FLAG_STORE

- SHOPIFY_CLI_THEME_TOKEN

- SHOPIFY_CLI_TTY

When I run "shopify theme push --development --verbose", this is the output:

2023-03-29T19:51:15.652Z: Running command theme push

I updated the Theme Access password in the pipeline to no effect.

Interestingly, when I configure my local environment to use the same theme access password and environment variables, the theme pushes with no issue.
