Craco with jest 27 createTransformer and _cracoConfig undefined with react-scripts 5

[kelbyers]

I'm using react-scripts 5.0.1, and get this error when running craco test:

TypeError: Cannot read properties of undefined (reading '_cracoConfig')

The same changes mentioned in #425 fixed the issue, but updating to craco 6.4.5 did not resolve the issue.

What version of craco are you using?

[kelbyers]

I tried both 6.4.3 and 6.4.5. I currently have 6.4.3.

Try using craco 7 (it just moved from alpha to latest) because craco 6 does not support CRA 5.

I'll give it a try tomorrow. I'm also using craco-antd, which also uses craco-less, and those set their peer dependencies to exactly version 6.4.3. I can configure my environment to use craco 7 instead, though.

craco 7 did resolve my issues. Thanks! It was still a beta when I looked earlier, and I didn't think to check if it had been released when I ran into the issue.
