Failed to deserialize JSON to REST_Error
Question

After upgrading two Outsystems plataforms (dev and production environments) to version 10.0.302.0 from version 9, lifetime stopped syncing changes to the servers. The error log shows this message: "Failed to deserialize JSON to REST_Error: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.

Does anyone have a clue on where to look for?


Thanks in advance,

Márcio Lima.

Hi Thiago,


The support team solved it for me, so I don't know what it was.
