Hi @yenda!

Strange, looks like for some reason it doesn't stripe out flow types 🤔 Do you have a custom setup or something? How can I reproduce this issue?

[yenda]

Hi @Kureev ,

I am not really familiar with javascript ecosystem so I am not sure what you mean by striping flow types.
Is it related to flowconfig ? Here is our project flowconfig file https://github.com/status-im/status-react/blob/develop/.flowconfig

What part of my setup would be relevant to you besides the project itself ?

[yenda]

I just deleted my repo and re-cloned it and the error disappeared

[vitamin-deaner]

I had the exact same issue. Yenda's turn it off and back on again approach miraculously worked for me too. thanks

I have the same issue in an iOS project. Re-cloning did not help.

[zaidqureshi2]

cleaning my node_module folder helped, almost same as recloning

[robrichard]

I had [email protected] in my yarn.lock. Recreating the yarn.lock installed v6.22.0 and fixed this issue.

[sibelius]

I have the same issue, any other fix?

i just removed "?" from the file and it worked
