Hi @Gabriel Mendizabal,

Did you try rebuiling the Teams app package? If you’re uploading to Teams App Studio, re‑export the agent package and re‑upload. Please make sure the manifest schema matches the latest Teams requirements.

Also, these are the possible reasons:

Agent configuration issues: A topic contains invalid variables, broken links, or missing required settings. A Power Automate flow connected to the agent has broken connections.

Manifest validation failure: The Teams app package generated during publishing has invalid metadata or outdated schema.

Service-side issues: Microsoft has acknowledged intermittent publishing failures (BadRequestException, ConnectorRequestFailure) in March 2026 affecting Teams distribution

Would be please surf this for furthre clue?

I am sure some clues I tried to give. If these clues help to resolve the issue brought you by here, please don't forget to check the box Does this answer your question? At the same time, I am pretty sure you have liked the response!

Hi @Haque, I'm also experiencing the same issue in my company. Some users in my organization can´t install the PVA Bot when I send them the link. They get that error. That has never happened before, I don't know what to do.
