basemap [ERROR]: Option -B parsing failure. Correct syntax:
-B Specify both (1) basemap frame settings and (2) axes parameters.
Frame settings are modified via an optional single invocation of -B[<axes>][+b][+g<fill>][+i[<val>]][+n][+o<lon>/<lat>][+s<subtitle>][+t<title>][+w[<pen>]][+x<fill>]⏎
…[+y<fill>][+z<fill>]
Axes parameters are specified via one or more invocations of -B[p|s][x|y|z]<intervals>[+a<angle>|n|p][+e[l|u]][+f][+l|L<label>][+p<prefix>][+s|S<secondary_label>]⏎
…[+u<unit>
<intervals> is composed of concatenated [<type>]<stride>[l|p] sub-strings. See basemap documentation for more details and examples of all settings.
