... 275 frames trimmedEnvironment
Bitbucket Server or Data Center version 6.8.2
Cause
There is a blank space next to the SSH port number, making the value be considered a string, and Bitbucket Server fails to format the string value as number, causing the java.lang.NumberFormatException.
Solution
The SSH port is stored in the database, so in order to update it the following steps should be followed:
⚠️ Before making any modifications to the database, ensure you have recent working backup of the database that you can restore from if needed.
Connect to the database using a SQL client
Run this database agnostic SQL command:
UPDATE plugin_setting SET key_value = REPLACE(key_value, '7999 ', '7999') WHERE key_name = 'stash.ssh.settings'Restart Bitbucket Server to apply the change
