building client errors: ERROR in node_modules/apollo-utilities/lib/util/mergeDeep.d.ts(2,52): error TS2370: A rest parameter must be of an array type.

we’re trying to build our angular app in docker but apollo errors: ERROR in node_modules/apollo-utilities/lib/util/mergeDeep.d.ts(2,52): error TS2370: A rest parameter must be of an array type. we’ve already updated all our dependencies to the latest version to try and fix this but no luck. Any ideas would be most welcome.

Intended outcome:

building the client in docker

Actual outcome:

ERROR in node_modules/apollo-utilities/lib/util/mergeDeep.d.ts(2,52): error TS2370: A rest parameter must be of an array type.

I can’t test it right now but downgrading apollo-utilities to 1.0.22 might work. let me know how it goes if you give it a try.

Likely duplicate of https://github.com/apollographql/apollo-client/issues/4506.

tl;dr If you can update the typescript package to at least 3.0, this error should go away, per https://github.com/apollographql/apollo-client/issues/4501#issuecomment-468001034. Since the original poster seems to be using typescript@3.3.3333, I would ask that they double-check there are no other copies of the typescript package in use.
