I am trying to call a function that is parented to a sealed class - when I try to access the method in iOS I get the following (is this a known issue):

this is the source that includes the toJson() method

@dazza5000 It's very hard to read these very long snippets. Can you share a set of files one could run (not involving a server or API calls) to reproduce the issue?

[dazza5000]

I think this issue is with using kotlinx.serialization in a framework that is exported and used in another project

[dazza5000]

im not certain all of the kotlinx.serialization binaries end up in the shared project

[louiscad]

@dazza5000 Can you show the Json { } config?

[dazza5000]

it is the default config

[louiscad]

Then it might not be the one you're looking for and might cause such issues because ¯\_ಠ_ಠ_/¯

[dazza5000]

How would I modify the config to make it the one I'm looking for?

[louiscad]

Try setting ignoreUnknownKeys to true, and also other settings you might need.

[dazza5000]

Also, none of the kotlinx serialization imports show up as valid, but the probject builds

[louiscad]

You put stuff in the Json { } that you pass to KotlinxSerializer

[louiscad]

You have multiple issues it seems. Can you share a project that has the exact same build files, modules, and the same gradle.properties ?
