请教关于设置动态关联

 

我在脚本中设置动态关联,运行场景后,抛出如下错误:51Testing软件测试网#z(g~zX5s2l
Action.c(8): Error -27190: No match found for the requested parameter "WCSParam_Diff1". Check whether the requested boundaries exist in the response data. Also, if the data you want to save exceeds 256 bytes, use web_set_max_html_param_len to increase the parameter size   [MsgId: MERR-27190]51Testing软件测试网!x \ V#K\&Jg'k:};\
