Type VectorSource<Feature<Geometry>> is not assignable to type VectorSource<FeatureLike>

this ts issue not happen in ol 9.1.0 happen in 9.2.0

@codeflyA Sorry, I cannot reproduce this. But since there are several thumbs-up on this, can anyone affected by this issue share a minimal reproduction repository?

[ahocevar]

Never mind. Able to reproduce now.

[ahocevar]

@codeflyA Does your project have a tsconfig.json? I can only reproduce the issue in projects without a tsconfig.json.

Does the issue go away when you add a tsconfig.json? If you have one already, please share a minimal reproduction repository.

[ahocevar]

@codeflyA #15831 should fix this. At least in the case that I could reproduce, it does.

@alok-runner That's a different issue, because ol/source/Cluster is affected here. But it's similar enough for me to attempt adding a fix in #15831.

@codeflyA - Can you try your example with the latest ol@dev version?

[codeflyA]

issue fix in 9.2.1-dev.1715868460880 thanks

[tschaub]

You can get the fix in the ol@9.2.1 release.

[zdila]

I have the same problem also in 9.2.1 and 9.2.4. In version 9.1.0 it compiles without errors.

[ahocevar]

Please use ol@dev, which contains the final fixes to these issues.
