Hey everybody,I have following problem:I created a flow that makes a POST Callout to my own API.It works perfectly fine when I trigger the flow, but when a different user tries it it says:The callout couldn't access the endpoint. You might not have the required permissions, or the named credential "Test_API" might not exist.Steps I already did:1. I created a Named Credential and Set up the Principal.2. I created a Permission Set, => External Credential Principal Access => and added all External Credential Principal Name to the set3. I assigned that Permission set to the User.4. To overcome this, I tried to change the Running Behaviour of the Flow to "System Context Without Sharing—Accesses all data", w/o any success.Anyone aware what else I can try?Thank you in advance.
