Metro: React Native is not building since metro 0.24.5 has been released

[SMJ93]

Since version 0.24.5 has been released we have been unable to run our react-native project on iOS and Android:

 BUNDLE  [android, dev] ./index.android.js ░░░░░░░░░░░░░░░░ 0.0% (0/1), failed.

error: bundling failed: Error: invalid value for dynamic deps behavior: `null`

    at _combinedTickCallback (internal/process/next_tick.js:95:7)

We reverted back to 0.24.4 and the app bundled as expected.

Environment:

• "react-native": "0.52.0"
• "react": "16.2.0"

Let me know if you need any more details.

Thanks for reporting! I'm looking into it

[thomasobrien99]

I am having the same issue. Thanks for the quick response!

[rafeca]

Sorry folks! This has been caused because we added a new config parameter to allow dynamic requires. But this new param is not handled by RN v0.52 and makes metro fail.

I'm going to publish a v0.24.6 version to fix that asap

[rafeca]

Version v0.24.6 published! Thanks for reporting it so fast 😄

Thank you, I found the right time, I was having this error since yesterday.

I had a similar error with 0.24.7. Moving back to 0.24.6 fixed it.

Metro Bundler ready.

Loading dependency graph...
BUNDLE [android, dev] ./index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1)
BUNDLE [android, dev] ./index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1)

i get this and the emulator screen shows nothing but "Loading from 10.0.2.2:8081" and nothing else...what do i do???

[SMJ93]

@Harish-Hk delete the app from your simulator, run git clean -xfd (this removed all .gitignore files) from your project root before running your project again.

I've had this problem in the past and cleaning the project / simulator has fixed it for me!

I'm still seeing this issue. None of the solutions above helped.
