Deploy Operation rejected. Error: Error parsing version string:. Path 'value[0].applicationDependencyVersion', line 1, position 276.; - Job Id : 9aca2f5a-9fc8-4892-b9fb-d6bf192a9b4f

Hello,

That error isn’t complaining about the platform/application values you showed (they’re fine and in the expected 4-part numeric format); it usually happens because the publish endpoint is parsing “applicationDependencyVersion” for an already-installed app in that tenant and one of them comes back empty or malformed, so the JSON parser blows up on value[0].applicationDependencyVersion before it even finishes the deploy. In practice: check Extension Management in the failing environments and look for any extension with a weird/short version (not W.X.Y.Z) or missing/odd dependency metadata, then update/uninstall that extension and retry; also make sure you’re using the latest Business Central administration PowerShell module, because older module/API combinations have been picky around version parsing. (Your app.json aligns with Microsoft’s expected version formatting rules for app.json properties and dependency versions.)

Regards,
Oussama Sabbouh
