Exactly the same thing. Yesterday everything worked well and I could Install the custom application with domains, but today I receive the same error 😕

rror while reading manifest.json: Invalid value(s) specified for validDomains[0]: "https://xx.xxx.xx"
Invalid value(s) specified for validDomains[1]: "https://xx.xxx.xx"
Invalid value(s) specified for validDomains[2]: "https://xx.xx.xx"

Very strange behaviour.
