| - | There are two common reasons for that: | ||
| - | * You run script from a different environment (under a different account/service; with a different configuration) than the GUI. See another [[faq_scheduler|F.A.Q.]] ((Although it covers a different topic, its recommendations are valid for this case as well.)) | ||
| - | * You have your [[session_configuration|session configured]] differently in the script and in the %%GUI%%. | ||
| - | * Use a [[ui_generateurl|Generate URL]] command to avoid common mistakes in manually typed URL's. \\ A common problem is [[session_url#special|special characters]] in some part of the [[session_url|session URL]] (typically a password or a username). | ||
| - | * Try using the %%GUI%% site from the script, using an ''open <site>'' command to see, to see if it makes the script working. Though do not use this solution for a production code. It's not recommended to [[scripting#configuration|rely on a GUI configuration in the script]]. | ||
| - | * Passphrase to an SSH private key is not a password, you need to specify it using ''[[scriptcommand_open|-passphrase]]'' switch, not in a password part of the session %%URL%%. | ||
| - | You can also enable a [[logging|session logging]] both in the %%GUI%% (on //[[ui_pref_logging|Logging page]]// of Preferences dialog) and the script (using a command-line parameter ''[[commandline|/log]]'') and compare the logs to find out what is different. Use a command-line parameter ''/loglevel=*'' to enable a password logging and check if a correct password is used. | + | ===== [[common]] Common Problems ===== |
| + | There are three common reasons why a script does not work, when a connectivity is otherwise possible | ||
| + | ==== Environment ==== | ||
| + | You run script from a different environment (under a different account/service; with a different configuration) than the GUI. | ||
| + | |||
| + | See another FAQ: [[faq_scheduler|*]] (Although it covers a different topic, its recommendations are valid for this case as well). | ||
| + | |||
| + | ==== [[configuration]] Configuration === | ||
| + | |||
| + | You have your [[session_configuration|session configured]] differently in the script and in the %%GUI%%. | ||
| + | * Use a [[ui_generateurl|Generate Session URL/Code]] command to avoid common mistakes in manually typed URL's or code; and to make sure all the settings from your GUI configuration is used in the script. \\ A common problem is [[session_url#special|special characters]] in some part of the [[session_url|session URL]] (typically a password or a username). \\ Further, some characters have special meaning in string literals in programming languages. If your password (or other credential) contains such special character, it needs to be escaped using the rules of the language. Notably in PowerShell, a dollar sign has special meaning in double-quoted string. Code generated by WinSCP escapes these too. | ||
| + | * Passphrase to an SSH private key is not a password, you need to specify it using ''[[scriptcommand_open|-passphrase]]'' switch, not in a password part of the session %%URL%%. | ||
| + | * With [[webdav|WebDAV]] and [[s3|S3]] protocols, it is possible that [[faq_root_path|you do not have an access to the root folder (bucket list in S3)]]. | ||
| + | |||
| + | ==== [[paths]] Paths ==== | ||
| + | |||
| + | You use different paths in the script than in the GUI. | ||
| + | * Always make sure you that use the //exact// paths that you see on the label above the [[ui_file_panel|file panel]] in the GUI. Use //Copy Path to Clipboard// command to avoid typing errors. | ||
| + | * Common mistake is using paths that are relative to the home folder as absolute paths. For example, when there's ''data'' folder in your ''/home/user'' folder, you cannot refer to the folder as ''/data''. Either use an absolute path ''/home/user/data'' (recommended) or relative path ''data''. | ||
| + | * Remote paths are case sensitive. So ''Data'' is not the same as ''data''. | ||
| + | |||
| + | ==== [[inputs]] Source and Destination Inputs ==== | ||
| + | |||
| + | Commands in scripting (like [[scriptcommand_put|''put'']] and [[scriptcommand_get|''get'']]) and some methods in .NET assembly (like [[library_session_getfiles|''Session.GetFiles'']] and [[library_session_putfiles|''Session.PutFiles'']]) do not take mere paths as inputs. The source input is expected to be a path terminated by a slash (a backslash when uploading) and followed by a [[file_mask|file mask]]. Similarly the destination input is expected to be a path also terminated by a slash (a backslash when downloading) followed by an optional [[operation_mask|operation mask]]. As a simple example, a command to upload all files in scripting should be like: | ||
| + | <code winscp> | ||
| + | put C:\source\path\* /destination/path/ | ||
| + | </code> | ||
| + | Similarly in .NET assembly: | ||
| + | <code csharp> | ||
| + | $session.PutFiles("C:\source\path\*", "/destination/path/").Check() | ||
| + | </code> | ||
| + | The trailing ''\*'' in the source path and the ''/'' in the destination path both matter. Read documentation of respective scripting commands or .NET assembly methods for details. In .NET assembly, in many cases, it's easier to use more specific methods like [[library_session_putfiletodirectory|''Session.PutFileToDirectory'']], [[library_session_putfilestodirectory|''Session.PutFilesToDirectory'']],[[library_session_getfiletodirectory|''Session.GetFileToDirectory'']] or [[library_session_getfilestodirectory|''Session.GetFilesToDirectory'']], as they do not have that strict interpretation of the inputs. | ||
| + | |||
| + | ===== [[logging]] Logging ===== | ||
| + | |||
| + | You can also enable a [[logging|session logging]] both in the %%GUI%% (on //[[ui_pref_logging|Logging page]]// of Preferences dialog) and the script (using a command-line parameter ''[[commandline#logging|/log]]'') and compare the logs to find out what is different. Use a command-line parameter ''[[commandline#logging|/loglevel=*]]'' to enable a password logging and check if a correct password is used. | ||
