Hi Tuyen, The attached error message contains the following lines:
Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1] Message: Invalid byte 1 of 1-byte UTF-8 sequence. This could be the sign of a misformatted XML. Is it possible that the XML was edited by hand? Please try the following things in order to rule out errors with the file: - Please unzip it and check if the extracted xml looks well formatted - Could you please check if the XML file starts with “<“? Also if the character encoding is correct. - Also please try to copy the faulty flow.xml.gz back to the 1.16.2 instance and try to start it using this config. Can it start up? If it does not help, could you please copy the first 3-4 lines from the flow.xml here? Thanks! Regards, Bence Simon > On 2023.
