So it seems that Summer 21 has created a new issue with using ExperienceBundle.

When trying to retrieve the ExperienceBundle from a Summer 21 (preview) instance sandbox, we get this error

problem: org.auraframework.throwable.quickfix.DefinitionNotFoundException: No COMPONENT named markup://c:suburbSearch found : [markup://c:xxxx_HelpAssistanceRegister, markup://c:xxxx_HelpAssistanceRegistration]

FYI - The component does exist (but is LWC vs the other 2 which are AURA) and does function as expected.

Salesforce Support has indicated that it is under investigation, but on a case for another issue.  I am wondering if anyone knows if there is a known issue for this?

Thanks

Tony
