After reading into that I agree. I'll close this issue and pursue that instead.

I'm glad I came across this. I'd experienced the same issue and logged an error on the Dynamic Entity Reference module.
I'd been advised to look into using the implementation of https://www.drupal.org/project/drupal/issues/3057545 🐛 ResourceTypeRepository wrongly assumes that all entity reference fields have the setting "target_type" Fixed .

Fixed patch issue

I've created an initial patch for this.

AlbionBrown → created an issue.

I made a mistake in my comments above. I hadnt realised I'd tried patch #16 some time ago and I already had the changes so thought the module's been updated include some of the changes. Patch #16 is still the correct one here. Sorry for spamming this thread!

I broke the patch file naming convention, so added another patch file update.

Update patch - small correction.

Version 2.0.1 of the module includes lots of code that patch #16 introduces. I've cleaned the patch down to the last remaining change.

This can be closed now, it's been too long for me to remember what the problem and solution was.
