prisma:getConfig fails with "Could not parse migration engine response: SyntaxError: Unexpected end of JSON input"

Bug description

When trying to run prisma migrate deploy on a production server I get the following error.

2021-07-16T09:19:08.582Z prisma:getConfig Using Query Engine Binary at: /node_modules/.prisma/client/query-engine-linux-arm-openssl-1.1.x

How to reproduce

1. Build a docker image using node:16.4-buster-slim.
2. Specify the env variables PRISMA_QUERY_ENGINE_BINARY , PRISMA_MIGRATION_ENGINE_BINARY, PRISMA_INTROSPECTION_ENGINE_BINARY, PRISMA_FMT_BINARY. This is because I ran into an issue with linux-arm-openssl-undefined. The application is running fine with those env variable now.
3. run prisma migrate deploy

Expected behavior

The migration happens successfully

BTW - Changing the variables to point to the right engines worked. Thanks for your support.

@janpio I added a comment to the other issue that was closed ☝️

nevermind. I found them under @prisma/engines. I will try to update the paths to use those.
