Composition-api: SSR issue moving from v0.21.0 to v0.22.0

[viktor-anyvan]

On SSR getting the following error:

[danielroe]

@viktor-anyvan Could you provide a reproduction? 🙏

[viktor-anyvan]

Sorry not really, its in our big project and not happening on local just on the servers (same node version). Any idea what should I try, how to debug?

[danielroe]

Ideally if you start with https://template.nuxtjs.org and then add in relevant code until you see the error, that would be brilliant.

If I had to guess, I would start by investigating adding 'vue' to your build.transpile array as we recently started transpiling vue/composition-api by default (to solve a different issue).

[viktor-anyvan]

Seems its related to https://nuxtjs.org/docs/2.x/configuration-glossary/configuration-modern/ we are using --modern=server for the build.

[viktor-anyvan]

@danielroe are you looking into this? Any idea?

[danielroe]

@viktor-anyvan I could really do with more info and a reproduction in order to look into this properly. What makes you think that it's related to modern: 'server'? Can you reproduce locally when you build/start the project? Are you relying on other libraries that also use the @vue/composition-api? (In which case, try adding them to your build.transpile as well to see if that fixes the issue - note that I've created issue #429 to track the issue.)

[viktor-anyvan]

Was not able to reproduce locally just on the servers, by removing --modern=server was fine or when I moved back to v0.21.0
Don't see any other libraries using @vue/composition-api by looking the yarn.lock file.

[danielroe]

@viktor-anyvan Would you be able to try with v0.23.0 to see if this fixes the issue for you?

[viktor-anyvan]

@danielroe thank you for the update, will check it soon.

[danielroe]

@viktor-anyvan Any updates?

[viktor-anyvan]

@danielroe all good now, thank you!

@viktor-anyvan Delighted to hear it :blush:
