Exception Loading Root with JSON Descriptor containing Enums

[dharmusharma1981]

protobuf.js version: <6.8.3>

Exception ExceptionsManager.js:65 (intermediate value)(intermediate value)(intermediate value) is not a function ``` Im trying to load json file which contains enums ` "PlatformType": { "values": { "UNKNOWN": 0, "RAY_DESKTOP": 1, "RAY_MOBILE": 2 } },

after drilling down the code

i find this Enum.fromJson is undefined in the libarary

That's strange, Enum.fromJSON should be there. What's the environment you are using protobuf.js in? Anything special?

[dharmusharma1981]

im using react native,
Used pbjs to convert proto to json format
with node

im using react native

I see. There have been similar issues in the past and iirc these are caused by recursive dependencies in the sources (enum.js requires something that again requires enum.js) that only react native isn't able to solve for some reason. This can be solved, usually, but requires checking all the dependencies and some reordering. Have you tried using the dist files instead?

[dharmusharma1981]

dist files work fine

I'm seeing this as well (version 0.51.0 of react-native). The circular dependency arises when namespace.js requires enum.js and enum.js requires namespace.js.

@dharmusharma1981 how were you able to import the dist files into the app?

[adambom]

Downgrading to version 6.8.0 worked for me (I was on 6.8.3).

for quick fix until PR merged:

yarn add LeonardPauli/protobuf.js#964-enum-circular-dep-react-native

(in essence 7 char diff from 6.8.6)

@dcodeIO any plans to merge this PR? We are blocked from using protobufjs in React Native due to this issue.
